There is h:panelGrid table with 2 columns.
It’s needed,that first column to be 30% and the second one 70% of whole table width.
Is there some configuration for such case?
Looks like columnClasses attribute applied for all columns,
and it’s needed specific CSS class for specific column.
Just use column-separated list of classes:
columnClasses="column1Class, column2Class". By documentation thecolumn1Classwill be used for the first column and thecolumn2Classfor the second column.
