Primefaces datatable frozen columns misallignment

We have a data table as shown in the image. There are 3 frozen columns and rest scrollable. The frozen columns are misalligned as shown. If frozen columns attribute is removed, the table looks properly. Any suggestions to solve the problem.

Solution 1:

I have had similar issues in the past with frozen datatable and using many different scripts across different posts I have found the below script works in ALL browsers and does not require you to set a height it will calculate it. As an added bonus it also triggers a browser event to force the table to resize properly.

synchronizeRowsHeight : function() {
   var $leftRows = $('.ui-datatable-frozenlayout-left').find('tr');
   var $rightRows = $('.ui-datatable-frozenlayout-right').find('tr');

   $leftRows.each(function(index) {
         var $leftRow = $(this);
         var $leftHeight = $leftRow.innerHeight();
         var $rightRow = $rightRows.eq(index);
         var $rightHeight = $rightRow.innerHeight();

         if ($rightHeight > $leftHeight) {
                $leftRow.innerHeight($rightHeight);
                var diff = $rightHeight - $leftRow.innerHeight();
                if (diff != 0)
                       $leftRow.innerHeight($rightHeight + diff);
         } else if ($rightHeight < $leftHeight) {
                $rightRow.innerHeight($leftHeight);
                var diff = $leftHeight - $rightRow.innerHeight();
                if (diff != 0)
                       $rightRow.innerHeight($leftHeight + diff);
         }
   })

   // fire a resize event to tell the table to repaint
   $(window).trigger('resize');
}

Solution 2:

Primefaces datatable frozen:

Frozen datatable has 2 parts left(fixed) and right(dynamic/scrollable)

<script type='text/javascript'>
function synchronizeRowsHeight() {
  //aligning table header row
  var $leftHeaderRow = $('.ui-datatable-frozenlayout-left .ui-datatable-scrollable-header-box tr');
  var $rightHeaderRow = $('.ui-datatable-frozenlayout-right .ui-datatable-scrollable-header-box tr');
  $leftHeaderRow.outerHeight(35);//height(px) in int    
  $rightHeaderRow.outerHeight(35);//height(px) in int   

  //aligning table data rows
   var $leftRows = $('.ui-datatable-frozenlayout-left .ui-datatable-scrollable-body tr');
   var $rightRows = $('.ui-datatable-frozenlayout-right .ui-datatable-scrollable-body tr');
   $leftRows.each(function (index) {
     var $leftRow = $leftRows.eq(index); 
     var $rightRow = $rightRows.eq(index);
     $rightRow.innerHeight($leftRow.innerHeight());
     $leftRow.innerHeight($rightRow.innerHeight());       
  });   
}
</script>

Call the above javascript function from your bean like

RequestContext.getCurrentInstance().execute("synchronizeRowsHeight();");
