y cant you use gridview instead of Table, since utlimatly the GridView will render as Html Table only.

You need to build an HTML Table based on the Datatable

sorry this the code
foreach (DataColumn column in ds.Tables[0].Columns)
{

lblresult.Text = column.ColumnName;
}

foreach (DataRow data in ds.Tables[0].Rows)
{

foreach (object item in data.ItemArray)
{
string temp = item.ToString();
}

}

Try this sample code to create an HTML table from Datatable, modify it as per your need.

C#

DataTable dt = new DataTable();
dt.Columns.Add("ID");
dt.Columns.Add("Name");
dt.Columns.Add("Address");
dt.Rows.Add(1, "karthik", "bangalore");
dt.Rows.Add(2, "sehwag", "delhi");
dt.Rows.Add(3, "kavya", "coimbatore");

string html = "<table><thead  ><tr>";
foreach (DataColumn column in dt.Columns)
    html += "<td>" + column.ColumnName + "</td>";
html += "</tr></thead><tbody>";
foreach (DataRow row in dt.Rows)
{
    html += "<tr>";
    foreach (DataColumn col in dt.Columns)
        html += "<td>" + row[col] + "</td>";
    html += "</tr>";
}
html += "</tbody></table>";


lbl.Text = html;
