我是c＃的新手，请帮助

I have created a dynamic table using c#. How do I set a colspan on the dynamic table using a textbox?

For example if I place a value 3 in the text box and click on Apply Span button then the colspan of a dynamic table should change accordingly.

I am new to c#, pls help

Thanks.

What I have tried:

<

    public partial class WebForm1 : System.Web.UI.Page
    {
    }

    protected void Page_Load(object sender, EventArgs e)
    {
    }

    public void CreateRuntime_Table()
    {
        int tblRows = int.Parse(txtrow.Text);
        int tblCols = int.Parse(txtcol.Text);

        Table tbl = new Table();
        tbl.BorderWidth = 3;
        tbl.BorderStyle = BorderStyle.Solid;
        tbl.ID = "myTable";

        for (int i = 1; i <= tblRows; i++)
        {

            TableRow tr = new TableRow();
            for (int j = 1; j <= tblCols; j++)
            {
                TableCell tc = new TableCell();
                TextBox txtbox = new TextBox();
                txtbox.Text = "Test Row:" + i + "Test Col:" + " " + j;
                //Add the control to the table cell
                tc.Controls.Add(txtbox);
                tr.Controls.Add(tc);
            }

            tbl.Rows.Add(tr);
        }

        form1.Controls.Add(tbl);
    }

    protected void Unnamed_Click(object sender, EventArgs e)
    {
        CreateRuntime_Table();
    }
