I have the column below and I will like to style the header. I have not had any luck doing this. Do you have an idea?
gridColumns.Add(grid.Column("PastDue", header: T("PastDue"), canSort: false, format: item => item.PastDue));
You can use jQuery to style column headers.
$("#myTable th:first").css({
"background-color": "green"
});
