Manage Table

A table in PowerPoint is an efficient way of displaying and portraying information. The information in a grid of cells (arranged in rows and columns) is straightforward and easy to understand.

Aspose.Slides provides the Table class, ITable interface, Cell class, ICell interface, and other types to allow you to create, update, and manage tables in all kinds of presentations.

Create Table from Scratch

1. Create an instance of the Presentation class.
2. Get a slide’s reference through its index.
3. Define an array of columnWidth.
4. Define an array of rowHeight.
5. Add an ITable object to the slide through the addTable method.
6. Iterate through each ICell to apply formatting to the top, bottom, right, and left borders.
7. Merge the first two cells of the table’s first row.
8. Access an ICell’s TextFrame.
9. Add some text to the TextFrame.
10. Save the modified presentation.

This PHP code shows you how to create a table in a presentation:

  # Instantiates a Presentation class that represents a PPTX file
  $pres = new Presentation();
  try {
    # Accesses the first slide
    $sld = $pres->getSlides()->get_Item(0);
    # Defines columns with widths and rows with heights
    $dblCols = array(50, 50, 50 );
    $dblRows = array(50, 30, 30, 30, 30 );
    # Adds a table shape to slide
    $tbl = $sld->getShapes()->addTable(100, 50, $dblCols, $dblRows);
    # Sets the border format for each cell
    for($row = 0; $row < java_values($tbl->getRows()->size()) ; $row++) {
      for($cell = 0; $cell < java_values($tbl->getRows()->get_Item($row)->size()) ; $cell++) {
        $cellFormat = $tbl->getRows()->get_Item($row)->get_Item($cell)->getCellFormat();
        $cellFormat::getBorderTop()->getFillFormat()->setFillType(FillType::Solid);
        $cellFormat::getBorderTop()->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.Color")->RED);
        $cellFormat::getBorderTop()->setWidth(5);
        $cellFormat::getBorderBottom()->getFillFormat()->setFillType(FillType::Solid);
        $cellFormat::getBorderBottom()->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.Color")->RED);
        $cellFormat::getBorderBottom()->setWidth(5);
        $cellFormat::getBorderLeft()->getFillFormat()->setFillType(FillType::Solid);
        $cellFormat::getBorderLeft()->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.Color")->RED);
        $cellFormat::getBorderLeft()->setWidth(5);
        $cellFormat::getBorderRight()->getFillFormat()->setFillType(FillType::Solid);
        $cellFormat::getBorderRight()->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.Color")->RED);
        $cellFormat::getBorderRight()->setWidth(5);
      }
    }
    # Merges cells 1 & 2 of row 1
    $tbl->mergeCells($tbl->getRows()->get_Item(0)->get_Item(0), $tbl->getRows()->get_Item(1)->get_Item(1), false);
    # Adds some text to the merged cell
    $tbl->getRows()->get_Item(0)->get_Item(0)->getTextFrame()->setText("Merged Cells");
    # Saves the presentation to Disk
    $pres->save("table.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Numbering in Standard Table

In a standard table, the numeration of cells is straightforward and zero-based. The first cell in a table is indexed as 0,0 (column 0, row 0).

For example, the cells in a table with 4 columns and 4 rows are numbered this way:

(0, 0)	(1, 0)	(2, 0)	(3, 0)
(0, 1)	(1, 1)	(2, 1)	(3, 1)
(0, 2)	(1, 2)	(2, 2)	(3, 2)
(0, 3)	(1, 3)	(2, 3)	(3, 3)

This PHP code shows you how to specify the numbering for cells in a table:

  # Instantiates a Presentation class that represents a PPTX file
  $pres = new Presentation();
  try {
    # Accesses first slide
    $sld = $pres->getSlides()->get_Item(0);
    # Defines columns with widths and rows with heights
    $dblCols = array(70, 70, 70, 70 );
    $dblRows = array(70, 70, 70, 70 );
    # Adds a table shape to slide
    $tbl = $sld->getShapes()->addTable(100, 50, $dblCols, $dblRows);
    # Sets the border format for each cell
    foreach($tbl->getRows() as $row) {
      foreach($row as $cell) {
        $cell->getCellFormat()->getBorderTop()->getFillFormat()->setFillType(FillType::Solid);
        $cell->getCellFormat()->getBorderTop()->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.Color")->RED);
        $cell->getCellFormat()->getBorderTop()->setWidth(5);
        $cell->getCellFormat()->getBorderBottom()->getFillFormat()->setFillType(FillType::Solid);
        $cell->getCellFormat()->getBorderBottom()->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.Color")->RED);
        $cell->getCellFormat()->getBorderBottom()->setWidth(5);
        $cell->getCellFormat()->getBorderLeft()->getFillFormat()->setFillType(FillType::Solid);
        $cell->getCellFormat()->getBorderLeft()->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.Color")->RED);
        $cell->getCellFormat()->getBorderLeft()->setWidth(5);
        $cell->getCellFormat()->getBorderRight()->getFillFormat()->setFillType(FillType::Solid);
        $cell->getCellFormat()->getBorderRight()->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.Color")->RED);
        $cell->getCellFormat()->getBorderRight()->setWidth(5);
      }
    }
    # Saves presentation to disk
    $pres->save("StandardTables_out.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Access Existing Table

1. Create an instance of the Presentation class.

2. Get a reference to the slide containing the table through its index.

3. Create an ITable object and set it to null.

4. Iterate through all IShape objects till the table is found.

   If you suspect the slide you are dealing with contains a single table, you can simply check all the shapes it contains. When a shape is identified as a table, you can typecast it as a Table object. But if the slide you are dealing with contains several tables, then you are better off searching for the table you need through its setAlternativeText(String value).

5. Use the ITable object to work with the table. In the example below, we added a new row to the table.

6. Save the modified presentation.

This PHP code shows you how to access and work with an existing table:

  # Instantiates the Presentation class that represents a PPTX file
  $pres = new Presentation("UpdateExistingTable.pptx");
  try {
    # Accesses the first slide
    $sld = $pres->getSlides()->get_Item(0);
    # Initializes null TableEx
    $tbl = null;
    # Iterates through the shapes and sets a reference to the table found
    foreach($sld->getShapes() as $shp) {
      if (java_instanceof($shp, new JavaClass("com.aspose.slides.Table"))) {
        $tbl = $shp;
        # Sets the text for the first column of the second row
        $tbl->get_Item(0, 1)->getTextFrame()->setText("New");
      }
    }
    # Saves the modified presentation to disk
    $pres->save("table1_out.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Align Text in Table

1. Create an instance of the Presentation class.
2. Get a slide’s reference through its index.
3. Add an ITable object to the slide.
4. Access an ITextFrame object from the table.
5. Access the ITextFrame IParagraph.
6. Align the text vertically.
7. Save the modified presentation.

This PHP code shows you how to align the text in a table:

  # Creates an instance of the Presentation class
  $pres = new Presentation();
  try {
    # Gets the first slide
    $slide = $pres->getSlides()->get_Item(0);
    # Defines columns with widths and rows with heights
    $dblCols = array(120, 120, 120, 120 );
    $dblRows = array(100, 100, 100, 100 );
    # Adds the table shape to the slide
    $tbl = $slide->getShapes()->addTable(100, 50, $dblCols, $dblRows);
    $tbl->get_Item(1, 0)->getTextFrame()->setText("10");
    $tbl->get_Item(2, 0)->getTextFrame()->setText("20");
    $tbl->get_Item(3, 0)->getTextFrame()->setText("30");
    # Accesses the text frame
    $txtFrame = $tbl->get_Item(0, 0)->getTextFrame();
    # Creates the Paragraph object for the text frame
    $paragraph = $txtFrame->getParagraphs()->get_Item(0);
    # Creates the Portion object for paragraph
    $portion = $paragraph->getPortions()->get_Item(0);
    $portion->setText("Text here");
    $portion->getPortionFormat()->getFillFormat()->setFillType(FillType::Solid);
    $portion->getPortionFormat()->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.Color")->BLACK);
    # Aligns the text vertically
    $cell = $tbl->get_Item(0, 0);
    $cell->setTextAnchorType(TextAnchorType::Center);
    $cell->setTextVerticalType(TextVerticalType::Vertical270);
    # Saves the presentation to disk
    $pres->save("Vertical_Align_Text_out.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Set Text Formatting on Table Level

1. Create an instance of the Presentation class.
2. Get a slide’s reference through its index.
3. Access an ITable object from the Slide.
4. Set the setFontHeight(float value) for the text.
5. Set the setAlignment(int value) and setMarginRight(float value).
6. Set the setTextVerticalType(byte value).
7. Save the modified presentation.

This PHP code shows you how to apply your preferred formatting options to the text in a table:

  # Creates an instance of the Presentation class
  $pres = new Presentation("simpletable.pptx");
  try {
    # Let's assume that the first shape on the first slide is a table
    $someTable = $pres->getSlides()->get_Item(0)->getShapes()->get_Item(0);
    # Sets the table cells' font height
    $portionFormat = new PortionFormat();
    $portionFormat::setFontHeight(25);
    $someTable->setTextFormat($portionFormat);
    # Sets the table cells' text alignment and right margin in one call
    $paragraphFormat = new ParagraphFormat();
    $paragraphFormat::setAlignment(TextAlignment->Right);
    $paragraphFormat::setMarginRight(20);
    $someTable->setTextFormat($paragraphFormat);
    # Sets the table cells' text vertical type
    $textFrameFormat = new TextFrameFormat();
    $textFrameFormat::setTextVerticalType(TextVerticalType::Vertical);
    $someTable->setTextFormat($textFrameFormat);
    $pres->save("result.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Get Table Style Properties

Aspose.Slides allows you to retrieve the style properties for a table so that you can use those details for another table or somewhere else. This PHP code shows you how to get the style properties from a table preset style:

  $pres = new Presentation();
  try {
    $table = $pres->getSlides()->get_Item(0)->getShapes()->addTable(10, 10, array(100, 150 ), array(5, 5, 5 ));
    $table->setStylePreset(TableStylePreset->DarkStyle1);// change the default style preset theme

    $pres->save("table.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Lock Aspect Ratio of Table

The aspect ratio of a geometric shape is the ratio of its sizes in different dimensions. Aspose.Slides provided the setAspectRatioLocked property to allow you to lock the aspect ratio setting for tables and other shapes.

This PHP code shows you how to lock the aspect ratio for a table:

  $pres = new Presentation("pres.pptx");
  try {
    $table = $pres->getSlides()->get_Item(0)->getShapes()->get_Item(0);
    echo("Lock aspect ratio set: " . $table->getGraphicalObjectLock()->getAspectRatioLocked());
    $table->getGraphicalObjectLock()->setAspectRatioLocked(!$table->getGraphicalObjectLock()->getAspectRatioLocked());// invert

    echo("Lock aspect ratio set: " . $table->getGraphicalObjectLock()->getAspectRatioLocked());
    $pres->save("pres-out.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }
