JTable inside JPanel - edges hidden. - SunnyAkuma - Apr 12, 2015

I made this GUI, used a Panel that contains a Table.

Functionality is fine , but My table's sides are cut , about 5 pixels is hidden from each side of the table.

I tried to increase the size of the panel , but the table just stretches and the sides are still hidden , It's irritating cause Half scrollbar isn't visible , and of the left side the first digit of the numbers isn't visible

can someone run this programe and see what I mean
can someone provide me with a solution ?

Your problem is

PHP Code 


<?php 
maintainanceRepariTable.setPreferredScrollableViewportSize(new Dimension(700,200));
breakdownRepariTable.setPreferredScrollableViewportSize(new Dimension(700,200)); 

so try and delete those.

You need to remove those lines. The scrollbar will show when you have enough rows - that's what they're supposed to do.

Thanks that worked.

Can you tell me how to add a Horizontal Scroll bar too?
I don't need it here , but just for the sake of knowing.

Hmm, I dunno. I think you'd have to define the sizes of each columns. Like, if you set them all at fixed widths that altogether add up to a total width greater than the scroll pane, then it will add a horizontal scroll bar by itself.
