I did the code change which helped me to resolve the issue . Hope its helps you

In class : GroupableTableHeaderUI

cellRect.width = aColumn.getWidth() + columnMargin; // Remove the column margin which is adding 1px to the width of the header column

New line will have : cellRect.width = aColumn.getWidth()

In class : ColumnGroup

comment line : // width += margin;

This has helped me to align the table columns and the header column . Please find below image

BorderLayout.CENTER is the simple answer, but notice if you want to add more than one item (which is typically the case) then you must understand that when using BORDERLAYOUT.NORTH for example there must exist an object that has a layout of BORDERLAYOUT.SOUTH in that case JAVA understands that these object are on top of each other , same applies to EAST and WEST
