cannot print JTable column header

[cluenek]

Hello Folks,

I'm Fairly new to java. I"m using JBuilder 3, java 1.2. My goal is
to print out a GridControl. I referenced Sun's tutorial on how to
print a JTable. Not to much info. on printing gridcontrols out there.
I'm basically instantiating a PrintData class with a Gridcontol.
Then setting the JdbTable dataset to pick up the rows, columns and
headers. All prints fine except for the header. The header does seem
to be set. When testing I can get columns names. Any insight would
be much appreciated.

Thanks

public class PrintData implements Printable
{
private GridControl gridControlToPrint;
private final static int POINTS_PER_INCH = 27;

public PrintData(GridControl aGridControl)
{
gridControlToPrint = aGridControl;
}

private JTable modifiedTable()
{
JdbTable tempTable = new JdbTable();

tempTable.setDataSet(gridControlToPrint.getDataSet());
tempTable.setSize(gridControlToPrint.getSize());

for (int row = 0; row < tempTable.getRowCount(); row++)
{
for (int col = 0; col < tempTable.getColumnCount(); col++)
{
Object temp = tempTable.getValueAt(row,col);

if (temp == null)
tempTable.setValueAt(" ",row,col);
else
tempTable.setValueAt(temp.toString(),row,col);
}
}

return (JTable)tempTable;
}

public int print(Graphics g, PageFormat pageFormat, int page)
{
return printTable(g, pageFormat, page);

}
else
