我点击编辑按钮之后出现确定按钮和取消按钮，可是点取消按钮上一行突然出现确定按钮和取消按钮，再点上一行还出现，请问这是为什么？ TableRow rows = new TableRow();
for (int j = 0; j < 3; j++)
{
TableCell cell = new TableCell();
if (j == 0)
{
Label lbl = new Label();
lbl.ID = "Label" + i.ToString();
lbl.Text = enumerator.Key.ToString();
cell.Controls.Add(lbl);
rows.Controls.Add(cell);
//tbcontent.Controls.Add(rows); 放到外面去
}
else if(j==1)
{
同上
}
else
{
}
}
tbcontent.Controls.Add(rows);
