When you need to show/hide table you can use below code
<script type="text/JavaScript">
<!--
function show(id)
{
if (document.getElementById(id).style.display == 'none')
{
document.getElementById(id).style.display = '';
}
}
//-->
<!--
function hide(id)
{
document.getElementById(id).style.display = 'none';
}
//-->
</script>
By default you can assign id and have values like below
<table id="tblA" style="DISPLAY: none" cols="1" cellpadding="2">
