Ok gang, I have a report that exports to pdf using CloudExport. The report exports just fine, except that the table row-group footer background color is not applied. The table head is the same dark gray. Can someone help me out here? This is the report.view.php for the grouping:

....        
"bottom"=>"<td colspan=\"6\"><b>Total for user {USRNAME}</b></td><td><b>pdholidayAmount</b></td><td></td><td><b>pdMealAmount</b></td><td><b>pdptoAmount</b></td><td><b>pdhrsAmount</b></td><td><b>totalhoursAmount</b></td>"
           ],
           ],
               "cssClass"=>array(
        "table"=>"table table-bordered",
        "tr"=>function($row){
            if($row["PTO"]=="*"){ return "yellowCss";}
            if($row["IsHoliday"]>= 8){ return "orangeCss";}
        },
        "th"=>function($columnName){
             if($columnName == "SEQ_NO_CLCK_IN" || $columnName == "SEQ_NO_CLCK_OUT"){ return 'nodisplay';}
        },
        "td"=>function($row,$columnName){
            if($columnName=="IsHoliday" && $row["IsHoliday"] != '0'){
            return "bold";
            } elseif($columnName=="PtoToPay" && $row["PtoToPay"] != '0'){
            return "bold";
            } else {return"";}
        },
        "tf"=>function($columnName){
            return "darker";
        }
    ),

It is the "bottom" that is not getting the proper css styling for the row.

Hi Sebastian, Yes I am aware of Chrome not printing background by default, and I already have the code you sent in my css file for this report. Just for a sanity-check I added it directly to the report view as you suggested but unfortunately there was no change. We'll be ok without, but it is odd that we cannot get headless over-ridden to print as desired.
