Coloring row problem of JTable

Question

Hi!
I'm the beginer and have a problem while coloring rows in my table. The problem is as follows:
i need to color the whole row when i click a single cell of this row. Everything is ok until i click another cell of another row. When i do it all the row between first and last clicked become colored!
I tryed manipulating table.setSelectionMode(i) - but nothing!
My very simple code:
DefaultTableCellRenderer renderer = new DefaultTableCellRenderer()
            public Component getTableCellRendererComponent(JTable table,Object value, boolean isSelected, boolean hasFocus, int row, int column)
                Component cell = super.getTableCellRendererComponent(table,value, isSelected, hasFocus, row, column);
                if (isSelected) {cell.setBackground(Color.LIGHT_GRAY);return cell;}
                return cell;
for(int i=0; i<table.getColumnCount(); i++)
            table.getColumnModel().getColumn(i).setCellRenderer(renderer);
Please help!
PS I cant use Ctrl button in my program because all the changes in table are in table.isEnable(false)-mode-it is the condition of my work.

Karl already gave the correct answer: once you touched any Color property of a DefaultTableCellRenderer, you have to do it always, that is in any of the logic branches. That's because DTCR has a nasty color "memory" which basically is the net result of inapproriate subclassing (no compelling reason for a renderer to-be a component) and frozen api (couldn't add a setRendererXXColor) at the particular moment of evolution when it was needed. (Our SwingX wiki about swingx renderer/highlighter support has more details)
BTW, if I interpret your code snippet correctly, you are after a different selection color for all columns? If so you can set that color globally for your table instance (hint: api doc is your friend :-), no need for a custom renderer.
