使用openxml合並excel中的相鄰單元格

Question

我想使用openxml在excel中合並五個相鄰的單元格。我試圖通過添加一個單元格來對下面的代碼片段進行修改，但它不起作用。它只適用於兩個單元格。 如果我想合並多個細胞，我該怎么辦？

// Given a document name, a worksheet name, and the names of two adjacent cells, merges the two cells.
    // When two cells are merged, only the content from one cell is preserved:
    // the upper-left cell for left-to-right languages or the upper-right cell for right-to-left languages.
    private static void MergeTwoCells(Worksheet worksheet, string cell1Name, string cell2Name)
    {
        // Open the document for editing.
        // Verify if the specified cells exist, and if they do not exist, create them.
        //CreateSpreadsheetCellIfNotExist(worksheet, cell1Name);
        //CreateSpreadsheetCellIfNotExist(worksheet, cell2Name);

            MergeCells mergeCells;
            if (worksheet.Elements<MergeCells>().Count() > 0)
            {
                mergeCells = worksheet.Elements<MergeCells>().First();
            }
            else
            {
                mergeCells = new MergeCells();

                // Insert a MergeCells object into the specified position.
                if (worksheet.Elements<CustomSheetView>().Count() > 0)
                {
                    worksheet.InsertAfter(mergeCells, worksheet.Elements<CustomSheetView>().First());
                }
                else if (worksheet.Elements<DataConsolidate>().Count() > 0)
                {
                    worksheet.InsertAfter(mergeCells, worksheet.Elements<DataConsolidate>().First());
                }
                else if (worksheet.Elements<SortState>().Count() > 0)
                {
                    worksheet.InsertAfter(mergeCells, worksheet.Elements<SortState>().First());
                }
                else if (worksheet.Elements<AutoFilter>().Count() > 0)
                {
                    worksheet.InsertAfter(mergeCells, worksheet.Elements<AutoFilter>().First());
                }
                else if (worksheet.Elements<Scenarios>().Count() > 0)
                {
                    worksheet.InsertAfter(mergeCells, worksheet.Elements<Scenarios>().First());
                }
                else if (worksheet.Elements<ProtectedRanges>().Count() > 0)
                {
                    worksheet.InsertAfter(mergeCells, worksheet.Elements<ProtectedRanges>().First());
                }
                else if (worksheet.Elements<SheetProtection>().Count() > 0)
                {
                    worksheet.InsertAfter(mergeCells, worksheet.Elements<SheetProtection>().First());
                }
                else if (worksheet.Elements<SheetCalculationProperties>().Count() > 0)
                {
                    worksheet.InsertAfter(mergeCells, worksheet.Elements<SheetCalculationProperties>().First());
                }
                else
                {
                    worksheet.InsertAfter(mergeCells, worksheet.Elements<SheetData>().First());
                }
            }

            // Create the merged cell and append it to the MergeCells collection.

            string s1 = cell1Name + ":" + cell2Name ;
            MergeCell mergeCell = new MergeCell() { Reference = s1 };
            mergeCells.Append(mergeCell);

            worksheet.Save();

    }

您無需更改代碼。 如果要合並多個單元格，只需確保cell1Name是要合並的單元格的左上角單元格 ，而cell2Name是右下角的單元格 （即A1：B2將合並單元格A1，A2，B1和B2） 。

此外，僅保留左上角單元格中的值（或從右到左文本的右上角）。
