asp.net, itextshape format

I have the following code working fine to create table with itextsharp,
my question is i will have more tables like table1, table2 for something.
How can i make default format for all of the table?
like I want all of the table has totalwidth = 540f?

Thanks


PdfPTable table = new PdfPTable(2); //Table with 2 columns
            //========================================================
            //table format
            table.TotalWidth = 540f;
            table.LockedWidth = true;
            var titleFont = FontFactory.GetFont("Arial", 18, Font.BOLD);
            var subTitleFont = FontFactory.GetFont("Arial", 14, Font.BOLD);
            var boldTableFont = FontFactory.GetFont("Arial", 12, Font.BOLD);
            var endingMessageFont = FontFactory.GetFont("Arial", 10, Font.ITALIC);
            var bodyFont = FontFactory.GetFont("Arial",8, Font.NORMAL);
            table.HorizontalAlignment = 0;
            table.SpacingBefore = 10;
            table.SpacingAfter = 10;
            table.DefaultCell.Border = 1;
            //table.SetWidths(new int[] { 1, 4 });
