Hi everyone,

            I am currently trying to print a multipage JTable but the
the thing is on the left hand side of the JTable does not have any grid
lines and i have tried to draw a rectangle around the jTable before
printing it but nothing is happening.

           Another thing is that when the JTable goes on the next page
for printing there are trailing grid lines on the previous page. I have
tried clipping and translating it but nothing works.

          You guys can try removing the painting of the Table Headers
to get a clearer picture if you want

Here is the code with a mini test program so you guys can run the
program and see what i mean

}

     Basically i am trying to print a JTable with the option of table
headers as a complete grid and withou any trainling lines

               I know that 1.5 now has printing but i need to use this
way of printing(i.e. by using the printable interface) for the program
to suit a special kind of need

Any help is greatly appreciated

Thank You

Yous Sincerely
