Manage Rows and Columns

To allow you to manage a table’s rows and columns in a PowerPoint presentation, Aspose.Slides provides the Table class, ITable interface, and many other types.

Set First Row as Header

  1. Create an instance of the Presentation class and load the presentation.
  2. Get a slide’s reference through its index.
  3. Create an ITable object and set it to null.
  4. Iterate through all IShape objects to find the relevant table.
  5. Set the table’s first row as its header.

This Python code shows you how to set a table’s first row as its header:

import aspose.slides as slides

# Instantiates the Presentation class
with slides.Presentation("table.pptx") as pres:
    # Accesses the first slide
    sld = pres.slides[0]

    # Initializes the null TableEx
    tbl = None

    # Iterates through the shapes and sets a reference to the table
    for shp in sld.shapes:
        if type(shp) is slides.Table:
            tbl = shp

    # Sets the first row of a table as its header 
    tbl.first_row = True
    
    # Saves the presentation to disk
    pres.save("table_out.pptx", slides.export.SaveFormat.PPTX)

Clone Table’s Row or Column

  1. Create an instance of the Presentation class and load the presentation,
  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 add_table(x, y, column_widths, row_heights) method.
  6. Clone the table row.
  7. Clone the table column.
  8. Save the modified presentation.

This Python code shows you how to clone a PowerPoint table’s row or column:

 import aspose.slides as slides

# Instantiates the Presentation class
with slides.Presentation() as presentation:

    # Accesses the first slide
    sld = presentation.slides[0]

    # Defines columns with widths and rows with heights
    dblCols =  [50, 50, 50] 
    dblRows =  [50, 30, 30, 30, 30] 

    # Adds a table shape to the slide
    table = sld.shapes.add_table(100, 50, dblCols, dblRows)

    # Adds some text to the row 1 cell 1
    table.rows[0][0].text_frame.text = "Row 1 Cell 1"

    # Adds some text to the row 1 cell 2
    table.rows[1][0].text_frame.text = "Row 1 Cell 2"

    # Clones Row 1 at the end of table
    table.rows.add_clone(table.rows[0], False)

    # Adds some text to the row 2 cell 1
    table.rows[0][1].text_frame.text = "Row 2 Cell 1"

    # Adds some text to the row 2 cell 2
    table.rows[1][1].text_frame.text = "Row 2 Cell 2"

    # Clones Row 2 as 4th row of table
    table.rows.insert_clone(3,table.rows[1], False)

    # Clones first column at the end
    table.columns.add_clone(table.columns[0], False)

    # Clones 2nd column at 4th column index
    table.columns.insert_clone(3,table.columns[1], False)
    
    # Saves the presentation to disk
    presentation.save("table_out.pptx", slides.export.SaveFormat.PPTX)

Remove Row or Column from Table

  1. Create an instance of the Presentation class and load the presentation,
  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 add_table(x, y, column_widths, row_heights) method.
  6. Remove the table row.
  7. Remove the table column.
  8. Save the modified presentation.

This Python code shows you how to remove a row or column from a table:

import aspose.slides as slides

with slides.Presentation() as pres:
    slide = pres.slides[0]
    colWidth =  [100, 50, 30] 
    rowHeight =  [30, 50, 30] 

    table = slide.shapes.add_table(100, 100, colWidth, rowHeight)
    table.rows.remove_at(1, False)
    table.columns.remove_at(1, False)
    pres.save("TestTable_out.pptx", slides.export.SaveFormat.PPTX)

Set Text Formatting on Table Row Level

  1. Create an instance of the Presentation class and load the presentation,
  2. Get a slide’s reference through its index.
  3. Access the relevant ITable object from the slide.
  4. Set the first-row cells' font_height.
  5. Set the first-row cells' alignment and margin_right.
  6. Set the second-row cells' text_vertical_type.
  7. Save the modified presentation.

This Python code demonstrates the operation.

import aspose.slides as slides

# Creates an instance of the Presentation class
with slides.Presentation() as presentation:
    
    slide = presentation.slides[0]

    someTable = slide.shapes.add_table(100, 100, [100, 50, 30], [30, 50, 30])

    # Sets first row cells' font height
    portionFormat = slides.PortionFormat()
    portionFormat.font_height = 25
    someTable.rows[0].set_text_format(portionFormat)

    # Sets first row cells' text alignment and right margin
    paragraphFormat = slides.ParagraphFormat()
    paragraphFormat.alignment = slides.TextAlignment.RIGHT
    paragraphFormat.margin_right = 20
    someTable.rows[0].set_text_format(paragraphFormat)

    # Sets the second row cells' text vertical type
    textFrameFormat = slides.TextFrameFormat()
    textFrameFormat.text_vertical_type = slides.TextVerticalType.VERTICAL
    someTable.rows[1].set_text_format(textFrameFormat)
	
  # Saves the presentation to Disk
    presentation.save("result.pptx", slides.export.SaveFormat.PPTX)

Set Text Formatting on Table Column Level

  1. Create an instance of the Presentation class and load the presentation,
  2. Get a slide’s reference through its index.
  3. Access the relevant ITable object from the slide.
  4. Set the first-column cells' font_height.
  5. Set the first-column cells' alignment and margin_right.
  6. Set the second-column cells' text_vertical_type.
  7. Save the modified presentation.

This Python code demonstrates the operation:

import aspose.slides as slides

# Creates an instance of the Presentation class
with slides.Presentation() as pres:
    slide = pres.slides[0]
    someTable = slide.shapes.add_table(100, 100, [100, 50, 30], [30, 50, 30])

    # Sets first column cells' font height
    portionFormat = slides.PortionFormat()
    portionFormat.font_height = 25
    someTable.columns[0].set_text_format(portionFormat)

    # Sets first column cells' text alignment and right margin 
    paragraphFormat = slides.ParagraphFormat()
    paragraphFormat.alignment = slides.TextAlignment.RIGHT
    paragraphFormat.margin_right = 20
    someTable.columns[0].set_text_format(paragraphFormat)

    # Sets second column cells' text vertical type
    textFrameFormat = slides.TextFrameFormat()
    textFrameFormat.text_vertical_type = slides.TextVerticalType.VERTICAL
    someTable.columns[1].set_text_format(textFrameFormat)

    # Saves the presentation to Disk
    pres.save("result.pptx", slides.export.SaveFormat.PPTX)

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 Python code shows you how to get the style properties from a table preset style:

import aspose.slides as slides

with slides.Presentation() as pres:
    table = pres.slides[0].shapes.add_table(10, 10, [100, 150], [5, 5, 5])
    table.style_preset = slides.TableStylePreset.DARK_STYLE1
    pres.save("table.pptx", slides.export.SaveFormat.PPTX)
