# 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.Table = table;
                XWPFTableRow tabRow = new XWPFTableRow(targetRow, target);
                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;
                        for (int r = 0; r < para.Runs.Count; r++)
                        {
                            CT_R targetRun = targetPhs.AddNewR();
                            XWPFRun run = para.Runs[r];
                            targetRun.rPr = run.GetCTR().rPr;
                            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!
