Scrollable Table with fixed header and first column

From a long time ,I was searching for a script that can satisfy my need to have a scrollable table with fixed header and fixed First column,I tried many scripts but some of them were not compatible with the application I want to make(I was trying to make a calendar for aircraft activity in a flight management system with drag drop functionality.) and some script was not multi browser capable so I decided to write my own script using jquery.I am not a master in jquery but I know its basic use.
so I want to share this code with the one who want to create their own scrollable table with flexible content for the table.





<html>
<head>
<script type="text/javascript" src="http://jqueryui.com/latest/jquery-1.3.2.js"></script>
<script>
$(document).ready(function(){
fnAdjustTable();
});

fnAdjustTable=function(){

var colCount=$('#firstTr>td').length; //get total number of column

var m=0;
var n=0;
var brow='mozilla';
jQuery.each(jQuery.browser, function(i, val) {
if(val==true){

brow=i.toString();
}
});
$('.tableHeader').each(function(i){
if(m<colCount){

if(brow=='mozilla'){
$('#firstTd').css("width",$('.tableFirstCol').innerWidth());//for adjusting first td

$(this).css('width',$('#table_div td:eq('+m+')').innerWidth());//for assigning width to table Header div
}
else if(brow=='msie'){
$('#firstTd').css("width",$('.tableFirstCol').width());

$(this).css('width',$('#table_div td:eq('+m+')').width()-2);//In IE there is difference of 2 px
}
else if(brow=='safari'){
$('#firstTd').css("width",$('.tableFirstCol').width());

$(this).css('width',$('#table_div td:eq('+m+')').width());
}
else{
$('#firstTd').css("width",$('.tableFirstCol').width());

$(this).css('width',$('#table_div td:eq('+m+')').innerWidth());
}
}
m++;
});

$('.tableFirstCol').each(function(i){
if(brow=='mozilla'){
$(this).css('height',$('#table_div td:eq('+colCount*n+')').outerHeight());//for providing height using scrollable table column height
}else if(brow=='msie'){

$(this).css('height',$('#table_div td:eq('+colCount*n+')').innerHeight()-2);
}else{
$(this).css('height',$('#table_div td:eq('+colCount*n+')').height());
}
n++;
});



}

//function to support scrolling of title and first column
fnScroll=function(){

$('#divHeader').scrollLeft($('#table_div').scrollLeft());
$('#firstcol').scrollTop($('#table_div').scrollTop());


}

</script>
</head>

  3. This was great, but I wanted code that would adjust EITHER the header cell width/height, OR the table cell width/height.

    after 4 days of dinking around, I determined that to change the width of a cell in the data table, you have to first change the width of the table itself by the same amount.
    Could be that there's a better way to do this, but this is what I came up with:
    [in my example, I changed the way the selector for the data cells works, and I added row and column classes to the data cells, but I don't think this was strictly necessary]

    the changed code looks like:
    - um, looks like I can't cut and paste into this textbox??

    well, anyways, basically you check if the header or data cell is larger, and adjust acccordingly. If it's the data cell you're widening, then widen the table by the same amount.

  4. Seems like the table does not scroll correctly or even align the columns vertically if you have spanned columns in the header. Any idea?

  5. for spanned columns ,I think if u give same colspan to all table in use than it should work ,not pretty sure.

  7. great script, but when a column is empty it goes wrong in the header. For example if you remove all the values of column 4 in your example, the header of column 4 is not visible anymore.

    I'm not familiar with javascript. I think it's not difficult to take the maximum width of the header or the maximum width of the column as the column width. Anybody that can help me?

  8. Very nice. The horizontal scrolling has some problems when changing text direction (i.e putting dir="rtl" in the body tag ). Any idea how to solve this ?
