条件格式

条件格式是一项高级 Microsoft Excel 功能，允许您将格式应用于单元格或单元格区域，并根据单元格的值或公式的值更改格式。例如，您可以让单元格仅在单元格的值大于 500 时显示为粗体。当单元格的值满足条件时，指定的格式将应用于单元格。如果单元格的值不满足条件，则使用默认格式。在 Microsoft Excel 中，选择格式， 然后条件格式打开条件格式对话框。

Microsoft Excel 中的条件格式

Aspose.Cells 支持在运行时对单元格应用条件格式。这篇文章解释了如何。

应用条件格式

Aspose.Cells 通过两种方式支持条件格式：

• 使用设计器电子表格.
• 在运行时创建条件格式.

使用设计器电子表格

开发人员可以在 Microsoft Excel 中创建包含条件格式的设计器电子表格，然后使用 Aspose.Cells 打开该电子表格。Aspose.Cells 加载并保存设计器电子表格，同时保留任何条件格式设置。要了解有关设计器电子表格的更多信息，请阅读什么是设计器电子表格.

在运行时应用条件格式

Aspose.Cells 支持在运行时应用条件格式。

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java
// Path to source file
String dataDir = Utils.getSharedDataDir(ConditionalFormattingatRuntime.class) + "data/";
// Instantiating a Workbook object
Workbook workbook = new Workbook();
Worksheet sheet = workbook.getWorksheets().get(0);
ConditionalFormattingCollection cfs = sheet.getConditionalFormattings();

// The first method:adds an empty conditional formatting
int index = cfs.add();
FormatConditionCollection fcs = cfs.get(index);

// Sets the conditional format range.
CellArea ca1 = new CellArea();
ca1.StartRow = 0;
ca1.StartColumn = 0;
ca1.EndRow = 0;
ca1.EndColumn = 0;

CellArea ca2 = new CellArea();
ca2.StartRow = 0;
ca2.StartColumn = 0;
ca2.EndRow = 0;
ca2.EndColumn = 0;

CellArea ca3 = new CellArea();
ca3.StartRow = 0;
ca3.StartColumn = 0;
ca3.EndRow = 0;
ca3.EndColumn = 0;

fcs.addArea(ca1);
fcs.addArea(ca2);
fcs.addArea(ca3);

// Sets condition formulas.
int conditionIndex = fcs.addCondition(FormatConditionType.CELL_VALUE, OperatorType.BETWEEN, "=A2", "100");

FormatCondition fc = fcs.get(conditionIndex);

int conditionIndex2 = fcs.addCondition(FormatConditionType.CELL_VALUE, OperatorType.BETWEEN, "50", "100");

// Saving the Excel file
workbook.save(dataDir + "CFAtRuntime_out.xls");

设置字体

在 Microsoft Excel 中设置字体

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java
// Path to source file
String dataDir = Utils.getSharedDataDir(SettingFontStyle.class) + "data/";
		
// Instantiating a Workbook object
Workbook workbook = new Workbook();
FormatCondition fc = null;
Style style = fc.getStyle();
Font font = style.getFont();
font.setItalic(true);
font.setBold(true);
font.setStrikeout(true);
font.setUnderline(FontUnderlineType.DOUBLE);
font.setColor(Color.getBlack());
fc.setStyle(style);
// Saving the Excel file
workbook.save(dataDir + "SFontStyle_out.xls");

设置边框

在 Microsoft Excel 中设置边框

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java
// Path to source file
String dataDir = Utils.getSharedDataDir(SetBorder.class) + "data/";
		
// Instantiating a Workbook object
   Workbook workbook = new Workbook();
   Worksheet sheet = workbook.getWorksheets().get(0);

   // Adds an empty conditional formatting
   int index = sheet.getConditionalFormattings().add();
   FormatConditionCollection fcs = sheet.getConditionalFormattings().get(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.CELL_VALUE, OperatorType.BETWEEN, "50", "100");
   // Sets the background color.
   FormatCondition fc = fcs.get(conditionIndex);
   
Style style = fc.getStyle();
style.setBorder(BorderType.LEFT_BORDER, CellBorderType.DASHED, Color.fromArgb(0, 255, 255));
style.setBorder(BorderType.TOP_BORDER, CellBorderType.DASHED, Color.fromArgb(0, 255, 255));
style.setBorder(BorderType.RIGHT_BORDER, CellBorderType.DASHED, Color.fromArgb(0, 255, 255));
style.setBorder(BorderType.RIGHT_BORDER, CellBorderType.DASHED, Color.fromArgb(255, 255, 0));
fc.setStyle(style);

设置模式

在 Microsoft Excel 中设置单元格模式

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java
// Path to source file
String dataDir = Utils.getSharedDataDir(SetPattern.class) + "data/";

// Instantiating a Workbook object
Workbook workbook = new Workbook();
Worksheet sheet = workbook.getWorksheets().get(0);

// Adds an empty conditional formatting
int index = sheet.getConditionalFormattings().add();
FormatConditionCollection fcs = sheet.getConditionalFormattings().get(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.CELL_VALUE, OperatorType.BETWEEN, "50", "100");
// Sets the background color.
FormatCondition fc = fcs.get(conditionIndex);

Style style = fc.getStyle();
style.setPattern(BackgroundType.REVERSE_DIAGONAL_STRIPE);
style.setForegroundColor(Color.fromArgb(255, 255, 0));
style.setBackgroundColor(Color.fromArgb(0, 255, 255));
fc.setStyle(style);
