C# 使用NPOI在word文档的表格中绘制对角线

直接上代码吧，NPOI的word处理中没有直接绘制对角线的方法，下面的代码可以做出对角线效果

public void TableDrawDiagonalLine(XWPFTable table, int row = 0, int col = 0)
        {
            CT_TblBorders tblBorders = new CT_TblBorders();
            tblBorders.AddNewTop().val = ST_Border.none;
            tblBorders.AddNewLeft().val = ST_Border.none;
            tblBorders.AddNewBottom().val = ST_Border.none;
            tblBorders.AddNewRight().val = ST_Border.none;
            tblBorders.AddNewInsideH().val = ST_Border.none;
            tblBorders.AddNewInsideV().val = ST_Border.none;
            table.GetCTTbl().tblPr.tblBorders = tblBorders;
            var cell = table.GetRow(row).GetCell(col);
            CT_TcPr tcpr = cell.GetCTTc().AddNewTcPr();
            CT_Border border1 = new CT_Border();
            border1.val = ST_Border.single;
            border1.sz = 10;
            border1.color = "000000"; // Black color
            border1.space = (ulong)4; // Space between lines
            border1.shadow = ST_OnOff.True;
            tcpr.tcBorders = new CT_TcBorders();
            tcpr.tcBorders.tl2br = border1;
        }
