Remove the border of a table headerCell itext7 pdf

I am creating a table using itext7.

I can change the color of a regular cell. How can I change the border to Null of a header cell?

I cannot add a check to create a "false" headerCell as the table may be a mutli-column so I would like the cells to be atop each column.

Having this false headerCell would just be on the first cell generated.

I tried:

            //does not work.
            table.setBorder(null);

            //---------------------------does not work.
            table.addHeaderCell("one: ").setBorder(Border.NO_BORDER);
            table.addHeaderCell("two: ").setBorder(null).addStyle(normal);
            table.addHeaderCell("three: ").setBorder(null).addStyle(normal);

Your code is almost right. The problem is very simple and can be found in the next line:

table.addHeaderCell("one: ").setBorder(Border.NO_BORDER);

Notice that Table#addHeaderCell method returns Table not Cell object. So then you apply Border.NO_BORDER on Table.

The solution is:

table.addHeaderCell(new Cell().add("one: ").setBorder(Border.NO_BORDER));

Also if you want to set specific border on header/footer (the analog of Table border), write summat table.getHeader().setBorder(your border). Notice also that itext applys table border on header/footer too.

I also want to mention that invoking Table constructor as you do isn't 100% correct if you use itext 7.0.2+. If you want columns widths to be in a ratio 2 29 30 (or any else), call Table(UnitValue.createPercentArray(new float[]{2, 29, 30)) ;
