插入新行并使用OpenXML SDK 2.0移动现有的行
我正在使用OpenXML SDK 2.0将数据添加到电子表格模板，但我遇到了一个问题（因为我一直在使用OpenXML的一天不难相信）。 我不知道如何添加新行，同时推下新的行下面的所有行。
这是我正在使用的电子表格模板。 更确切地说，我想要实现的是将这些石板色的行移动到底部，同时向白色的行添加数据。
我目前使用的代码与MSDN上的代码相同 – 使用Open XML Format SDK 2.0创build文档（第2部分，共3部分）
我相信这个部分的代码是在这个部分：
sheetData.AppendChild(polaznikRow); 我也尝试过使用InsertAfter，InsertAt等。 但没有任何成功。
任何帮助，将不胜感激。
如果您将新行添加到空白工作表，本教程中的代码将起作用。 既然你有一个你正在使用的模板，那么你将需要做更多的工作，以便在工作表的中间添加一行。 您几乎需要使用相同的代码添加行，但是您必须手动更新插入的行之后的每一行的行索引。 您还必须更新合并的单元格引用和超链接引用。 可能还有更多，你必须更新，但我从来没有更新比这三件事情。 插入一行的主要方法如下：
/// <summary> /// Inserts a new row at the desired index. If one already exists, then it is /// returned. If an insertRow is provided, then it is inserted into the desired /// rowIndex /// </summary> /// <param name="rowIndex">Row Index</param> /// <param name="worksheetPart">Worksheet Part</param> /// <param name="insertRow">Row to insert</param> /// <param name="isLastRow">Optional parameter - True, you can guarantee that this row is the last row (not replacing an existing last row) in the sheet to insert; false it is not</param> /// <returns>Inserted Row</returns> public static Row InsertRow(uint rowIndex, WorksheetPart worksheetPart, Row insertRow, bool isNewLastRow = false) { Worksheet worksheet = worksheetPart.Worksheet; SheetData sheetData = worksheet.GetFirstChild<SheetData>(); Row retRow = !isNewLastRow ? sheetData.Elements<Row>().FirstOrDefault(r => r.RowIndex == rowIndex) : null; // If the worksheet does not contain a row with the specified row index, insert one. if (retRow != null) { // if retRow is not null and we are inserting a new row, then move all existing rows down. if (insertRow != null) { UpdateRowIndexes(worksheetPart, rowIndex, false); UpdateMergedCellReferences(worksheetPart, rowIndex, false); UpdateHyperlinkReferences(worksheetPart, rowIndex, false); // actually insert the new row into the sheet retRow = sheetData.InsertBefore(insertRow, retRow); // at this point, retRow still points to the row that had the insert rowIndex string curIndex = retRow.RowIndex.ToString(); string newIndex = rowIndex.ToString(); foreach (Cell cell in retRow.Elements<Cell>()) { // Update the references for the rows cells. cell.CellReference = new StringValue(cell.CellReference.Value.Replace(curIndex, newIndex)); } // Update the row index. retRow.RowIndex = rowIndex; } } else { // Row doesn't exist yet, shifting not needed. // Rows must be in sequential order according to RowIndex. Determine where to insert the new row. Row refRow = !isNewLastRow ? sheetData.Elements<Row>().FirstOrDefault(row => row.RowIndex > rowIndex) : null; // use the insert row if it exists retRow = insertRow ?? new Row() { RowIndex = rowIndex }; IEnumerable<Cell> cellsInRow = retRow.Elements<Cell>(); if (cellsInRow.Any()) { string curIndex = retRow.RowIndex.ToString(); string newIndex = rowIndex.ToString(); foreach (Cell cell in cellsInRow) { // Update the references for the rows cells. cell.CellReference = new StringValue(cell.CellReference.Value.Replace(curIndex, newIndex)); } // Update the row index. retRow.RowIndex = rowIndex; } sheetData.InsertBefore(retRow, refRow); } return retRow; }
那么这里是下面的帮助者方法来更新行索引，超链接和合并的单元格引用：
/// <summary> /// Updates all of the Row indexes and the child Cells' CellReferences whenever /// a row is inserted or deleted. /// </summary> /// <param name="worksheetPart">Worksheet Part</param> /// <param name="rowIndex">Row Index being inserted or deleted</param> /// <param name="isDeletedRow">True if row was deleted, otherwise false</param> private static void UpdateRowIndexes(WorksheetPart worksheetPart, uint rowIndex, bool isDeletedRow) { // Get all the rows in the worksheet with equal or higher row index values than the one being inserted/deleted for reindexing. IEnumerable<Row> rows = worksheetPart.Worksheet.Descendants<Row>().Where(r => r.RowIndex.Value >= rowIndex); foreach (Row row in rows) { uint newIndex = (isDeletedRow ? row.RowIndex - 1 : row.RowIndex + 1); string curRowIndex = row.RowIndex.ToString(); string newRowIndex = newIndex.ToString(); foreach (Cell cell in row.Elements<Cell>()) { // Update the references for the rows cells. cell.CellReference = new StringValue(cell.CellReference.Value.Replace(curRowIndex, newRowIndex)); } // Update the row index. row.RowIndex = newIndex; } } /// <summary> /// Updates the MergedCelss reference whenever a new row is inserted or deleted.

B2)</param> /// <returns>Row Index (ie. 2)</returns> public static uint GetRowIndex(string cellReference) { // Create a regular expression to match the row index portion the cell name. Regex regex = new Regex(@"\d+"); Match match = regex.Match(cellReference); return uint.Parse(match.Value); } /// <summary> /// Increments the reference of a given cell. This reference comes from the CellReference property /// on a Cell. /// </summary> /// <param name="reference">reference string</param> /// <param name="cellRefPart">indicates what is to be incremented</param> /// <returns></returns> public static string IncrementCellReference(string reference, CellReferencePartEnum cellRefPart) { string newReference = reference; if (cellRefPart != CellReferencePartEnum.None && !String.IsNullOrEmpty(reference)) { string[] parts = Regex.Split(reference, "([AZ]+)"); if (cellRefPart == CellReferencePartEnum.Column || cellRefPart == CellReferencePartEnum.Both) { List<char> col = parts[1].ToCharArray().ToList(); bool needsIncrement = true; int index = col.Count - 1; do { // increment the last letter col[index] = Letters[Letters.IndexOf(col[index]) + 1]; // if it is the last letter, then we need to roll it over to 'A' if (col[index] == Letters[Letters.Count - 1]) { col[index] = Letters[0]; } else { needsIncrement = false; } } while (needsIncrement && --index >= 0); // If true, then we need to add another letter to the mix. Initial value was something like "ZZ" if (needsIncrement) { col.Add(Letters[0]); } parts[1] = new String(col.ToArray()); } if (cellRefPart == CellReferencePartEnum.Row || cellRefPart == CellReferencePartEnum.Both) { // Increment the row number. A reference is invalid without this componenet, so we assume it will always be present. parts[2] = (int.Parse(parts[2]) + 1).ToString(); } newReference = parts[1] + parts[2]; } return newReference; }
还有一些额外的东西，你将需要：
/// <summary> /// Given a cell name, parses the specified cell to get the column name. /// </summary> /// <param name="cellReference">Address of the cell (ie. B2)</param> /// <returns>Column name (ie. A2)</returns> private static string GetColumnName(string cellName) { // Create a regular expression to match the column name portion of the cell name. Regex regex = new Regex("[A-Za-z]+"); Match match = regex.Match(cellName); return match.Value; } public enum CellReferencePartEnum { None, Column, Row, Both } private static List<char> Letters = new List<char>() { 'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z', ' ' };
感谢amurra的答案。 对于那些仍然无法做到的人来说，这里是缺less的部分
/// <summary> /// Given a cell name, parses the specified cell to get the column name. /// </summary> /// <param name="cellReference">Address of the cell (ie.
