Thank you for your inquiry.
To format the PDFLightTable cell please use the BeginCellLayoutEvent. Please find the sample from the below location regarding this.
{Installed version}\My Documents\Syncfusion\EssentialStudio\7.1.0.30\Windows\Pdf.Windows\Samples\2.0\Tables\Table Features
Online documentation regarding this:
