在工作表中应用条件格式

可能的使用场景

Aspose.Cells允许您添加各种条件格式,例如公式、高于平均值、颜色比例、数据条、图标集、前10名等。它提供了FormatCondition类,该类具有应用您选择的条件格式所需的所有方法。这是一些Get方法的列表。

在工作表中应用条件格式

以下示例代码演示了如何在单元格A1和B2上添加单元格值的条件格式。请查看代码生成的输出Excel文件,以及以下截图解释了代码在输出Excel文件上的效果。如果在单元格A2和B2中放入大于100的值,则从单元格A1和B2的红色填充颜色将消失。

示例代码

Aspose::Cells::Startup();
//For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-C
//Path of input
U16String dirPath(u"");
//Path of output
U16String outPath(u"");
//Path of output excel file
U16String outputApplyConditionalFormattingInWorksheet = outPath + u"outputApplyConditionalFormattingInWorksheet.xlsx";
//Create an empty workbook
Workbook wb;
//Access first worksheet
Worksheet ws = wb.GetWorksheets().Get(0);
//Adds an empty conditional formatting
int idx = ws.GetConditionalFormattings().Add();
FormatConditionCollection fcs = ws.GetConditionalFormattings().Get(idx);
//Set the conditional format range
CellArea ca = CellArea::CreateCellArea(u"A1", u"A1");
fcs.AddArea(ca);
ca = CellArea::CreateCellArea(u"B2", u"B2");
fcs.AddArea(ca);
//Add condition and set the background color
idx = fcs.AddCondition(FormatConditionType::CellValue, OperatorType::Between, u"=A2", u"100");
FormatCondition fc = fcs.Get(idx);
fc.GetStyle().SetBackgroundColor(Color{ 0xff,0xff ,0 ,0 });//Red
//User friendly message to test the output excel file.
U16String msgStr = u"Red color in cells A1 and B2 is because of Conditional Formatting. Put 101 or any value >100 in cell A2 and B2, you will see Red background color will be gone.";
ws.GetCells().Get(u"A10").PutValue(msgStr);
//Save the output excel file
wb.Save(outputApplyConditionalFormattingInWorksheet);
Aspose::Cells::Cleanup();
