for headerrow and Dynamic TextBox control

Table tbl = new Table(); // Creating a new table

TableHeaderRow header = new TableHeaderRow(); // Creating a header row
tbl.Rows.Add(header); // Add the header row to table tbl        

    // Creating Dynamic TextBox Control
TextBox t = new TextBox();
t.ID = "myTextBox"; // assing an ID

    // Now add this in a table row
TableRow rowNew = new TableRow(); // Creating a new table row
rowNew.Cells[0].Controls.Add(t);         // add the textbox control at cell zero
             // or you can add it as
rowNew.Controls.Add(t);
