NPOI 复制Word中的表格内容, 操作Word表格

操作NPOI中的Word表格,复制/克隆完整表格

---

##NPOI中没有提供复制表格/元素的方法,所以需要自己实现复制表格的方法

注意 以下操作均是操作docx文件

####操作Word文档需要操作XWPFDocument对象,复制表格需要操作XWPFTable对象

NPOI项目地址:https://github.com/tonyqus/npoi

代码如下,需要修改XWPFTable的构造函数:

public XWPFTable(CT_Tbl table, IBody part, XWPFTable source) // create new table by origin table { this.part = part; this.ctTbl = table; tableRows = new List<XWPFTableRow>(); XWPFTable target = this; target.ctTbl.tblPr = source.ctTbl.tblPr; target.ctTbl.tblGrid = source.ctTbl.tblGrid; for (int i = 0; i < source.Rows.Count; i++) { CT_Row targetRow = target.ctTbl.AddNewTr(); XWPFTableRow row = source.Rows[i]; targetRow.trPr = row.GetCTRow().trPr; targetRow.rsidR = row.GetCTRow().rsidR; targetRow.rsidTr = row.GetCTRow().rsidTr; targetRow.Table = table; XWPFTableRow tabRow = new XWPFTableRow(targetRow, this); tableRows.Add(tabRow); for (int c = 0; c < row.GetTableCells().Count; c++) { CT_Tc targetCell = targetRow.AddNewTc(); XWPFTableCell cell = row.GetTableCells()[c]; targetCell.tcPr = cell.GetCTTc().tcPr; for (int p = 0; p < cell.Paragraphs.Count; p++) { CT_P targetPhs = targetCell.AddNewP(); XWPFParagraph para = cell.Paragraphs[p]; targetPhs.pPr = para.GetCTP().pPr; targetPhs.rsidR = para.GetCTP().rsidR; targetPhs.rsidRPr = para.GetCTP().rsidRPr; targetPhs.rsidRDefault = para.GetCTP().rsidRDefault; targetPhs.rsidP = para.GetCTP().rsidP; for (int r = 0; r < para.Runs.Count; r++) { CT_R targetRun = targetPhs.AddNewR(); XWPFRun run = para.Runs[r]; targetRun.rPr = run.GetCTR().rPr; targetRun.rsidRPr = run.GetCTR().rsidRPr; targetRun.rsidR = run.GetCTR().rsidR; CT_Text text = targetRun.AddNewT(); text.Value = run.Text; } } } } } 

不理解的可以Clone github上的代码 拿工具看一下Word(docx)的结构就能大概明白了 不想修改构造函数的,可以使用反射直接操作元素 另外,NPOI毕竟是根据Java的POI改过来的,有些东西很多作者都没有实现,商用请慎重!
