Hi, Phil

Firstly, I would like to sincerely apologize for the delayed response as we have been experiencing an unusually high number of tickets. I am sorry that it has taken longer than usual to respond to your concern and your patience is highly appreciated.

- Sorry to disappoint you but unfortunately something like this is not possible to achieve with the plugin built-in features at the moment or some simple CSS.

Here is the suggestion from our customer that managed to achieve this :

"I actually created a fixed header and column using the translation of x and y (no absolute or fixed position used), very similar to the fixed header provided by weihs5  on this site, and here's one solution, take a look:

First of all, you gotta set the z-index for each component below:

jQuery("#table td").css({"z-index": "-1", "position": "relative"});
jQuery("table tr td:first-child").css({'z-index': '1', 'position': 'relative'});
jQuery("table th:first-child").css({ 'z-index':'2','position':'relative'});

Then you gotta add a listener on scroll like this:

jQuery('document').scroll(function () {   scrollBlock();
});

If your table is set to be scrollable, then you might want to add this in as well:

jQuery('.wdtscroll').scroll(function () { scrollBlock();
});

And here's the scrollBlock() part, it is ugly though, but it works for me though. (noted: the numbers work for my theme, if it is not working correctly on yours, then try to adjust the number until it fits.)

function scrollBlock(){  var table = document.querySelector('table');
var top = table.getBoundingClientRect().top;
top = document.body.className.search('admin') > 0 ? top - 32 : top + 3; // this value can change       
     var left = table.getBoundingClientRect().left;       
     if(left >= 20){ // before scrolling left (before transforming)           
                     if(top >= 0){ // before reaching header bar            
        jQuery("#table_1 thead th").css("transform", "translateY(0px)");      
               translate(jQuery("table th:nth-child(1)"), 0, 0);              
       translate(jQuery("table td:nth-child(1)"), 0, 0);                      
              } else{ // after reaching header bar                 
    jQuery("#table_1 thead th").css("transform", "translateY( " + (-top) + "px)");      
               translate(jQuery("table th:nth-child(1)"), 0, -top);              
       translate(jQuery("table td:nth-child(1)"), 0, 0);      
           }            } else { // after scrolling left                    
            if(top >= 0){                    jQuery("#table_1 thead th").css("transform", "translateY(0px)");  
                  translate(jQuery("table th:nth-child(1)"), -left + 46, 0);      
              translate(jQuery("table td:nth-child(1)"), -left + 46, 0);         
                           } else{        
             jQuery("#table_1 thead th").css("transform", "translateY( " + (-top) + "px)");          
           translate(jQuery("table th:nth-child(1)"), -left + 46, -top);            
         translate(jQuery("table td:nth-child(1)"), -left + 46, 0);         
            }                }            }
function translate(element, x, y) {
var translation = "translate(" + x + "px," + y + "px)"
element.css({      "transform": translation,     
  "-ms-transform": translation,          "-webkit-transform": translation,   
  "-o-transform": translation,      "-moz-transform": translation,   });
}

It is kind of messy, you definitely can't copy and paste and expect it to work for you. You need to spend some time to figure it out. Hope this helps everyone!"

So hopefully this can help you out.
