------------------------------------------------------------
It appears that the fix is really simple, when calling
"getTableCellRendererComponent", we should pass in "fakeTable" as the first
variable insteasd of null. Thanks!
--------------------- Source from ctakes code -------------------
final Component header =
fakeHeader.getDefaultRenderer().getTableCellRendererComponent( null,
"Available Pipe Bits", false, false, -1, -1 );
---------------------- source code -------------
public Component More ...getTableCellRendererComponent(JTable
table, Object value,
226 boolean isSelected,
227 boolean hasFocus,
228 int row, int column) {
229
230 boolean hasRollover = (column == getRolloverColumn());
