Dotted borders on DynaPDF Table

Is there a way to draw dotted borders on DynaPDF table??

Or Do I need to make table lines invisible and then draw the dotted lines?
Thats what I’m doing at this moment.

      call pdf.setLineDashPattern "3", 0
      call pdf.MoveTo(590,z+10.2)//largo,x
      call pdf.LineTo(20,z+10.2)//inicio,fin
      call pdf.StrokePath
      call pdf.setLineDashPattern "", 0

But dong this I have an Issue.
When a Row has more than 1 line, I can draw it properly.

Or it exists a way to know where is the Y position of the last line drawn and then pass it to the line.

Thanks
