In this demo, the customizeCell function changes the following elements:

  • Background color and font weight of group row cells
  • Font style of a footer cell

The customDrawCell function allows you to draw cells in a PDF document. The following parameters are available when you use this function:

  • doc
    An instance of the jsPDFDocument object.
  • rect
    A cell’s bounds.
  • gridCell
    Contains information about the source DataGrid cell.
  • pdfCell
    Contains settings applied to a cell in a PDF document.
  • cancel
    Set this parameter to true to prevent default painting logic.

This demo uses the customDrawCell function to paint cells in the "Website" column.
