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.
