but my selected row not changed

Your logic overrides the default selection of the row.

You need an additional check to make sure the row is not highlighted by default:

Component component = super.prepareRenderer(renderer,row,column);

if (!isRowSelected(row))
{
    // add custom highlighting here
}

return component; 

SeeTable Row Rendering for other row rendering examples.

Also, don't try to change a property of the table in the renderer.
