Question

我正在借助EPPlus库进行动态Excel创建，并且我拥有一个Excel，其数据如下所示：

Name     EmpCode   Department      attendance
Prashant  111      CSE         70% for Sep
Prashant  111      CSE         90% for Oct
XYZ       112      HR          50% for Sep
XYZ       112      HR          90% for Oct

我想要的是：如果当前的EmpCode等于下一行的值，则将这两列合并，这样预期的输出将为

我很确定每个empCode只会重复两次。

我尝试过的代码：

for (var rowNum = 1; rowNum <= ws.Dimension.End.Row; rowNum++)
 {
   var row = ws.Cells[string.Format("{0}:{0}", rowNum)];
 }

仅当empcode重复两次时，此代码才有效，但是您说过，您肯定会重复empcode两次，因此应该可以，只是规模很小。

一旦在电子表格中获取数据，就必须遍历数据集中的所有行。在循环的开头，您可以设置当前行的范围，在循环的末尾，您可以设置上一行的范围。如果设置了先前的范围，则需要评估每一行的列，以确定是否应将单元格合并在一起。

using (var p = new OfficeOpenXml.ExcelPackage(new FileInfo(@"c:\FooFolder\Foo.xlsx")))
{
    ExcelWorkbook wb = p.Workbook;
    ExcelWorksheet ws = wb.Worksheets[1];

    //create variable for previous range that will persist through each loop
    ExcelRange previousRange = null;

    //set position of first column to merge
    int mergecellBegin = 1;

    //set position of last column to merge
    int mergeCellEnd = 3;

    //create variable to check the cells of your rows
    bool areCellsEqual;

    //iterate through each row in the dataset

    for (var rowNum = 2; rowNum <= ws.Dimension.End.Row; rowNum++)
    {
        ExcelRange currentRange = ws.Cells[rowNum, 1, rowNum, mergeCellEnd];

        //will skip if we haven't set previous range yet
        if (previousRange != null)
        {
            //reset your check variable
            areCellsEqual = true;
            //check if all cells in the ranges are qual to eachother
            for (int i = 1; i <= mergeCellEnd; i++)
            {
                //if the cells from the ranges are not equal then set check variable to false and break the loop
                if (!currentRange[rowNum, i].Value.Equals(previousRange[rowNum - 1, i].Value))
                {
                    areCellsEqual = false;
                    break;
                }
            }

            //if all cells from the two ranges match, merge them together.
            if (areCellsEqual)
            {
                //merge each cell in the ranges
                for (int i = 1; i <= mergeCellEnd; i++)
                {
                    ExcelRange mergeRange = ws.Cells[rowNum - 1, i, rowNum, i];
                    mergeRange.Merge = true;
                }
            }
        }

        //sets the previous range to the current range to be used in next iteration
        previousRange = currentRange;
    }

    p.Save();
}

如何使用epPlus在Excel中检查下一个值是否相同并合并两行
