use SVG or VML or try some slow javascript:
<style type="text/css">
TD {width:1;height:1}
</style>
<script language="javascript">
var nRow = 50;
var nCol = 50;
function draw()
{
var i;
for (i=0; i < 50; i++)
{
document.all("tbl").rows[i].cells[10].style.backgroundColor = "red";
document.all("tbl").rows[i].cells[29].style.backgroundColor = "red";
}
for (i=0; i < 20; i++)
{
document.all("tbl").rows[0].cells[10+i].style.backgroundColor = "red";
document.all("tbl").rows[49].cells[10+i].style.backgroundColor = "red";
}
}
</script>
<body onload="draw()">
<table id="tbl" border="0" cellspacing="0" cellpadding="0">
<script language="javascript">
for (var i=0; i < nRow; i++)
{
document.write ("<tr>");
for (var j=0; j < nCol; j++)
document.write ("<td></td>");
document.write ("</tr>");
}
</script>
</table>
</body>Top
