C#——操作Word并导出PDF

   int tableRow = 6 ;
   int tableColumn = 6;
    //定义一个Word中的表格对象
   Microsoft.Office.Interop.Word.Table table = document.Tables.Add(document.Paragraphs[i].Range,
   tableRow, tableColumn, ref Nothing, ref Nothing);

 　　//默认创建的表格没有边框，这里修改其属性，使得创建的表格带有边框 
   table.Borders.Enable = 1;
   table.Cell(1, 1).Merge(table.Cell(2, 1));//纵向合并
   table.Cell(1, 1).Range.Text = "牌号/代码";

   table.Cell(1, 2).Merge(table.Cell(2, 2));//纵向合并
   table.Cell(1, 2).Range.Text = "标准编号";
