Response columns are (correctly) not rendered as separate columns, but that is not taken into account when setting the colspan attribute.



Fix is as follows:



change the block at line 1241 from:



if (!twistieSwitch) {

                        idex = this.findSpanLength(entry,x);<br/>
                        if(idex &gt; 0) td.colSpan = idex + 1<br/>
                        else if(idex == -1) td.colSpan = this.columns.length - x;<br/>
                    }<br/>
                    <br/>

to:



if (!twistieSwitch) {

idex = this.findSpanLength(entry,x);<br/>
if(idex &gt; 0) {<br/>
    td.colSpan = idex + 1;<br/>
} else if(idex == -1) {<br/>
    td.colSpan = this.columns.length - (x + ((this.responseColumn &gt; -1) ? 1 : 0));<br/>
}<br/>

}



and remove line 1331: (since not having a width causes the cell to expand to fill the available space).

        td.style.width = '50%';
