it, but if you are drawing 1000 rows then use a function like
function drawRow() {
document.write('<tr><td> </td><td> </td><td> </td></tr>');
}
and call it as is.
As for netscape, make each row a seperate table. You will have the overhead
of more table tags, but the page will be perceived by the user as a lot
faster.
If column widths are varying between rows, force them with spacer images:
<table>
<tr>
<td> </td>
<td> </td>
<td> </td>
</tr>
<tr>
<td><img src="" width="200" height="1"></td>
<td><img src="" width="100" height="1"></td>
<td><img src="" width="200" height="1"></td>
</tr>
</table>
which will make all rows a consistent sizing..
