Hi... i am actually creating a page i have included a drop down and in that values binding from 1 to 5 where if the person selcts 1 it should create a table with one row and 1 column if user selects 2 it should be one row with 2 columns and if he selects three automatically a table with 2 rows means 1st row 2 columns and 2nd row 1 column.. i tried it in js as follows:

XML

<asp:DropDownList ID="drpcolumns" runat="server" onchange="autogeneratetable(this);">
    <asp:ListItem Value="">Select number</asp:ListItem>
    <asp:ListItem Value="1">1</asp:ListItem>
    <asp:ListItem Value="2">2</asp:ListItem>
    <asp:ListItem Value="3">3</asp:ListItem>
    <asp:ListItem Value="4">4</asp:ListItem>
    <asp:ListItem Value="5">5</asp:ListItem>
</asp:DropDownList>

C#

function autogeneratetable(sel)
{
    var value = sel.options[sel.selectedIndex].value;
    alert(value);
    if(value != "Select Number")
    {
        var row;
        cell=new Array();
        tab=document.createElement('table');
        tab.setAttribute('id','newtable');
        //tbo=document.createElement('tbody');
        row=document.createElement('tr');
         for(c=0;c<value;c++)
        {
            var col = document.createElement('td'); // create column node
            row.appendChild(col);
        }
        tab.appendChild(row);
        document.getElementById('mytable').appendChild(tab);
    }
    else
    {
        document.getElementById("ctl00_ContentPlaceHolder1_lblerror").innerHTML = "Please Select a Number!";
    }
}

but i am not able to see the the table with line means border and columns... if i change the number its not showing any effect on page and no error and mytable in js is a div name i am appending table to div. Please can u help me in generating the table like in each row 2 columns. Or let me know whats wrong in my code. Thanking you in advance!
