I create a PDF document based on a table using `jsPDF` and `AutoTable`:

```
var doc = new jsPDF('p', 'pt');
   //columns and rows are arrays created from the table content
        doc.autoTable(columns, rows, {

        drawRow: function (row) {
            if (row.index == rows.length - 1) {
                console.log('last row');
                //TODO
            }
        },
        pageBreak: 'avoid',
        headerStyles: {
            fillColor: [239, 154, 154],
            textColor: [0, 0, 0],
            halign: 'center'
        },
        bodyStyles: {
            halign: 'center'
        },
        margin: {top: 60},
        theme: 'striped'
    });

    doc.save('table.pdf');

```

What I'm trying to do is setting a different background color for the last table row. As shown in the code above, I can detect when the last row is being drawn, however I can't manage to modify it. I have tried setting the `row.fillColor` using an RGB value, which seems to have no effect.

I also took a look at the [examples](https://github.com/simonbengtsson/jsPDF-AutoTable/blob/master/examples/examples.js), but couldn't find anything that could help me on that issue. Any ideas?
