设置Excel和ODS文件的条件格式。

介绍

条件格式是Microsoft Excel的高级功能,允许您对单元格或一系列单元格应用格式,并根据单元格的数值或公式的值更改格式。例如,只有当单元格的值大于500时,该单元格才会显示为粗体。当单元格的值满足条件时,会将指定的格式应用到单元格。如果单元格的值不符合格式条件,则使用单元格的默认格式。在Microsoft Excel中,选择格式,然后选择条件格式以打开条件格式对话框。

Aspose.Cells支持在运行时将条件格式应用于单元格。本文解释了如何实现这一点。它还解释了如何计算Excel用于颜色标度条件格式的颜色。

应用条件格式

Aspose.Cells支持多种方式的条件格式:

  • 使用设计师电子表格
  • 使用复制方法。
  • 在运行时创建条件格式。

使用设计者电子表格

开发人员可以在Microsoft Excel中创建一个包含条件格式的设计师电子表格,然后用Aspose.Cells打开该电子表格。Aspose.Cells加载并保存设计师电子表格,并保留任何条件格式设置。

使用复制方法

Aspose.Cells允许开发人员通过调用Range.Copy()方法将一个单元格的条件格式设置复制到工作表中的另一个单元格。

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
// Creating a file stream containing the Excel file to be opened
FileStream fstream = new FileStream(dataDir + "Book1.xlsx", FileMode.Open);
// Opening the Excel file through the file stream
Workbook workbook = new Workbook(fstream);
// Accessing the first worksheet in the Excel file
Worksheet worksheet = workbook.Worksheets[0];
// Copying conditional format settings from cell "A1" to cell "B1"
//worksheet.CopyConditionalFormatting(0, 0, 0, 1);
int TotalRowCount = 0;
for (int i = 0; i < workbook.Worksheets.Count; i++)
{
Worksheet sourceSheet = workbook.Worksheets[i];
Range sourceRange = sourceSheet.Cells.MaxDisplayRange;
Range destRange = worksheet.Cells.CreateRange(sourceRange.FirstRow + TotalRowCount, sourceRange.FirstColumn,
sourceRange.RowCount, sourceRange.ColumnCount);
destRange.Copy(sourceRange);
TotalRowCount = sourceRange.RowCount + TotalRowCount;
}
// Saving the modified Excel file
workbook.Save(dataDir + "output.xls");
// Closing the file stream to free all resources
fstream.Close();

在运行时应用条件格式

Aspose.Cells允许您在运行时添加和删除条件格式。下面的代码示例显示了如何设置条件格式:

  1. 实例化一个工作簿。
  2. 添加一个空的条件格式。
  3. 设置应用格式的范围。
  4. 定义格式条件。
  5. 保存文件。

在此示例之后还有许多其他小示例,演示如何应用字体设置、边框设置和图案。

Microsoft Excel 2007添加了更高级的条件格式设置,Aspose.Cells也支持。这里的示例说明了如何使用简单的格式设置,而Microsoft Excel 2007的示例则展示了如何应用更高级的条件格式设置。

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
string filePath = dataDir + "Book1.xlsx";
// Instantiating a Workbook object
Workbook workbook = new Workbook();
Worksheet sheet = workbook.Worksheets[0];
// Adds an empty conditional formatting
int index = sheet.ConditionalFormattings.Add();
FormatConditionCollection fcs = sheet.ConditionalFormattings[index];
// Sets the conditional format range.
CellArea ca = new CellArea();
ca.StartRow = 0;
ca.EndRow = 0;
ca.StartColumn = 0;
ca.EndColumn = 0;
fcs.AddArea(ca);
ca = new CellArea();
ca.StartRow = 1;
ca.EndRow = 1;
ca.StartColumn = 1;
ca.EndColumn = 1;
fcs.AddArea(ca);
// Adds condition.
int conditionIndex = fcs.AddCondition(FormatConditionType.CellValue, OperatorType.Between, "=A2", "100");
// Adds condition.
int conditionIndex2 = fcs.AddCondition(FormatConditionType.CellValue, OperatorType.Between, "50", "100");
// Sets the background color.
FormatCondition fc = fcs[conditionIndex];
fc.Style.BackgroundColor = Color.Red;
// Saving the Excel file
workbook.Save(dataDir + "output.xls");

设置字体

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
// Create directory if it is not already present.
bool IsExists = System.IO.Directory.Exists(dataDir);
if (!IsExists)
System.IO.Directory.CreateDirectory(dataDir);
// Instantiating a Workbook object
Workbook workbook = new Workbook();
// Adding a new worksheet to the Excel object
int i = workbook.Worksheets.Add();
// Obtaining the reference of the newly added worksheet by passing its sheet index
Worksheet worksheet = workbook.Worksheets[i];
// Accessing the "A1" cell from the worksheet
Aspose.Cells.Cell cell = worksheet.Cells["A1"];
// Adding some value to the "A1" cell
cell.PutValue("Hello Aspose!");
// Obtaining the style of the cell
Style style = cell.GetStyle();
// Setting the font weight to bold
style.Font.IsBold = true;
// Applying the style to the cell
cell.SetStyle(style);
// Saving the Excel file
workbook.Save(dataDir + "book1.out.xls", SaveFormat.Excel97To2003);

设置边框

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
public static void Run()
{
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
// Instantiating a Workbook object
Workbook workbook = new Workbook();
Worksheet sheet = workbook.Worksheets[0];
// Adds an empty conditional formatting
int index = sheet.ConditionalFormattings.Add();
FormatConditionCollection fcs = sheet.ConditionalFormattings[index];
// Sets the conditional format range.
CellArea ca = new CellArea();
ca.StartRow = 0;
ca.EndRow = 5;
ca.StartColumn = 0;
ca.EndColumn = 3;
fcs.AddArea(ca);
// Adds condition.
int conditionIndex = fcs.AddCondition(FormatConditionType.CellValue, OperatorType.Between, "50", "100");
// Sets the background color.
FormatCondition fc = fcs[conditionIndex];
fc.Style.Borders[BorderType.LeftBorder].LineStyle = CellBorderType.Dashed;
fc.Style.Borders[BorderType.RightBorder].LineStyle = CellBorderType.Dashed;
fc.Style.Borders[BorderType.TopBorder].LineStyle = CellBorderType.Dashed;
fc.Style.Borders[BorderType.BottomBorder].LineStyle = CellBorderType.Dashed;
fc.Style.Borders[BorderType.LeftBorder].Color = Color.FromArgb(0, 255, 255);
fc.Style.Borders[BorderType.RightBorder].Color = Color.FromArgb(0, 255, 255);
fc.Style.Borders[BorderType.TopBorder].Color = Color.FromArgb(0, 255, 255);
fc.Style.Borders[BorderType.BottomBorder].Color = Color.FromArgb(255, 255, 0);
workbook.Save(dataDir + "output.xlsx");
}

设置填充

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
// Instantiating a Workbook object
Workbook workbook = new Workbook();
Worksheet sheet = workbook.Worksheets[0];
// Adds an empty conditional formatting
int index = sheet.ConditionalFormattings.Add();
FormatConditionCollection fcs = sheet.ConditionalFormattings[index];
// Sets the conditional format range.
CellArea ca = new CellArea();
ca.StartRow = 0;
ca.EndRow = 5;
ca.StartColumn = 0;
ca.EndColumn = 3;
fcs.AddArea(ca);
// Adds condition.
int conditionIndex = fcs.AddCondition(FormatConditionType.CellValue, OperatorType.Between, "50", "100");
FormatCondition fc = fcs[conditionIndex];
fc.Style.Pattern = BackgroundType.ReverseDiagonalStripe;
fc.Style.ForegroundColor = Color.FromArgb(255, 255, 0);
fc.Style.BackgroundColor = Color.FromArgb(0, 255, 255);
workbook.Save(dataDir + "output.xlsx");
