检测工作表中的合并单元

本文介绍如何在工作表中获取合并的单元区域。

Aspose.Cells允许您在工作表中获取合并的单元区域。您也可以取消合并（拆分）它们。本文展示了使用Aspose.Cells API执行任务的最简单的代码。

该组件提供了能够获取所有合并单元格的方法。以下代码示例向您展示了如何在工作表中检测合并单元格。

// 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);

// Instantiate a new Workbook
// Open an existing excel file
Workbook wkBook = new Workbook(dataDir + "SampleInput.xlsx");
// Get a worksheet in the workbook
Worksheet wkSheet = wkBook.Worksheets["Sheet2"];
// Clear its contents
wkSheet.Cells.Clear();
           
// Get merged areas
CellArea[] areas = wkSheet.Cells.GetMergedAreas();
            
// Define some variables
int frow, fcol, erow, ecol, trows, tcols;
// Loop through the arraylist and get each cellarea
// To unmerge it
for (int i = 0; i < areas.Length; i++)
{
    frow = areas[i].StartRow;
    fcol = areas[i].StartColumn;
    erow = areas[i].EndRow;
    ecol = areas[i].EndColumn;

    trows = erow - frow + 1;
    tcols = ecol - fcol + 1;
    wkSheet.Cells.UnMerge(frow, fcol, trows, tcols);
}
dataDir = dataDir + "MergeTrial.out.xlsx";
// Save the excel file
wkBook.Save(dataDir);
