NewCell1.Style.Add("border-style","solid");
// new lebel
Label newLable1 = new Label();
count = count + 1; // just for change number in label text
newLable1.Text = "NewLabel = "+ count;
// adding lebel into cell
NewCell1.Controls.Add(newLable1);
// adding cells to row
NewRow1.Cells.Add(NewCell1);
//2ed cell
TableCell NewCell2 = new TableCell();
NewCell2.Style.Add("border-style", "solid");
Label newLable2 = new Label();
count = count + 1;
newLable2.Text = "NewLabel = " + count;
NewCell2.Controls.Add(newLable2);
NewRow1.Cells.Add(NewCell2);
//adding row into table
Table1.Rows.Add(NewRow1);
}

推荐答案
由于在
As given in the Question shared in Walid's answer, follow these steps:
-
创建表行的全局列表，是这样的：
Create a global list of table rows, something like:
List<TableRow> TableRows
在按钮，单击添加新创建的行列出：
In button click Add the newly created row to list:
TableRow row1=new TableRow();
TableRows.add(row1);
在的OnInit 方法只是所有的行添加到表：
In the OnInit method simply add all the rows to the table:
foreach ( TableRow row in TableRows )
{
Table1.Rows.Add(row);
}
这将解决您的问题。
