You can try this code to create table.

First place this markup in your aspx page like

<table id="tableContent" border="1" runat="server"></table>

Then Try This code in Page_Load like

protected void Page_Load(object sender, EventArgs e)
{
    HtmlTableRow row = new HtmlTableRow();
    HtmlTableCell cell = new HtmlTableCell();

    cell.ColSpan =3;
    cell.InnerText = "Record 1";
    row.Cells.Add(cell);
    tableContent.Rows.Add(row);

    row = new HtmlTableRow();
    cell = new HtmlTableCell();

    cell.InnerText = "1";
    row.Cells.Add(cell);

    cell = new HtmlTableCell();
    cell.InnerText = "2";
    row.Cells.Add(cell);

    cell = new HtmlTableCell();
    cell.InnerText = "3";
    row.Cells.Add(cell);

    tableContent.Rows.Add(row);

    row = new HtmlTableRow();
    cell = new HtmlTableCell();

    cell.InnerText = "a";
    row.Cells.Add(cell);

    cell = new HtmlTableCell();
    cell.InnerText = "b";
    row.Cells.Add(cell);

    cell = new HtmlTableCell();
    cell.InnerText = "c";
    row.Cells.Add(cell);

    tableContent.Rows.Add(row);


    row = new HtmlTableRow();
    cell = new HtmlTableCell();
    cell.InnerText = "m";
    row.Cells.Add(cell);

    cell = new HtmlTableCell();
    cell.InnerText = "n";
    row.Cells.Add(cell);

    cell = new HtmlTableCell();
    cell.InnerText = "o";
    row.Cells.Add(cell);

    tableContent.Rows.Add(row);

    row = new HtmlTableRow();
    cell = new HtmlTableCell();

    HtmlInputButton input = new HtmlInputButton();
    input.ID = "Button1";
    input.Value = "button";

    cell.ColSpan = 3;
    cell.Controls.Add(input);
    row.Cells.Add(cell);
    tableContent.Rows.Add(row);
}

Or You can try this, by storing cell values in 2D Array like

protected void Page_Load(object sender, EventArgs e)
{
    String[,] cellValues = { { "1", "2", "3" }, { "a", "b", "c" }, { "m", "n", "o" } };

    HtmlTableRow row = new HtmlTableRow();
    HtmlTableCell cell = new HtmlTableCell();

    cell.ColSpan = 3;
    cell.InnerText = "Record 1";
    row.Cells.Add(cell);
    tableContent.Rows.Add(row);

    for (int i = 0; i < cellValues.GetLength(0); i++)
    {
        row = new HtmlTableRow();
        for (int j = 0; j < cellValues.GetLength(1); j++)
        {
            cell = new HtmlTableCell();
            cell.InnerText = cellValues[i, j];
            row.Cells.Add(cell);
        }
        tableContent.Rows.Add(row);
    }

    row = new HtmlTableRow();
    cell = new HtmlTableCell();

    HtmlInputButton input = new HtmlInputButton();
    input.ID = "Button1";
    input.Value = "button";

    cell.ColSpan = 3;
    cell.Controls.Add(input);
    row.Cells.Add(cell);
    tableContent.Rows.Add(row);
}
