Hi,

I have one JSP page in that rows are arround 200 and column ranges from 4 to 100. when i am freezing first row of my table i have no performance issue even though how many columns get increased but as i am freezing first column of a table page is getting slower
while scrolling right.

This thing i am doing by using styleSheet code which i have pasted below

<style>
 
/* Setting the width and height of table througn DIV tag */
div#tbl-container {
  width:70%;
  height:70%;
 overflow: auto;
}
 
thead th, thead th.locked {
position:relative;
cursor:default;
}
 
/* This block of code will Freeze the header of table */
thead th {
left: expression(document.getElementById("tbl-container").scrollLeft); /* IE5+ only */
}
 
</style>

Since it is very urgent for me. Please suggest me ASAP.

Thanks,
Ashish

For browsers other than MSIE5 you might consider using position: fixed;  so that the CSS itself doesn't contain such an expression.  (I'm not familiar with this expression(.scrollLeft) business, but it seems like it requires actively recalculating where the th should begin, and it strikes me that it can't be terribly efficient.

what sort of data is in the first row and column? position: fixed, or alternative body, html 100% with absolute for MSIE could do what you're after:
