我的问题都在上面，大大们给的建议

  1. DropDown1.SelectedItem.Value为string型，要转化为int    
  2.   
  3. void Page_Load(Object sender, EventArgs e) {   
  4.   
  5.         int numrows = int.Parse(DropDown1.SelectedItem.Value);///将DropDown1值转换为int型   
  6.         int numcells = int.Parse(DropDown2.SelectedItem.Value);   
  7.         for (int j = 0; j < numrows; j++) {   
  8.             TableRow r = new TableRow();   
  9.             for (int i = 0; i < numcells; i++)   
  10.             {   
  11.                 TableCell c = new TableCell();   
  12.                 //TableCell 为单元格 c.Controls.Add 意思是在单元格中添加控件，new LiteralControl 创建了LiteralControl 控件   
  13.                   //显示第几行第几列   
  14.                 c.Controls.Add(new LiteralControl("行" + j.ToString() + ", 列" + i.ToString                                                                                          
  15.                 r.Cells.Add(c); //将Tablecell添加到table的row中                       
  16.             }   
  17.             Table1.Rows.Add(r);// 将行添加到table中   
  18.         }   
  19.     }   
  20.   
  21.   
  22. 就是动态来添加table的操作
