Hello everyone,
i have an Object array columns that i pass to the constructor of JTable, but for some reason the column names are not visible in my table.
private final Object[] columns = {"Zeit", "Termin"};
private Object[][] rows;
//the next line fills the two-dimensional rows-array
fillRows();
//here the constructor
JTable table = new JTable(rows, columns);
table.setColumnSelectionAllowed(false);
table.setDragEnabled(false);
          table.setSelectionMode(ListSelectionModel.SINGLE_INTERVAL_SELECTION);
TableColumnModel colModel = table.getColumnModel();
TableColumn column = colModel.getColumn(1);
column.setCellRenderer(new BookedCellRenderer(new int[] {3,4}));What are possible reasons/sollutions for this problem?

Gosh, thanks! Usually i always use a jscrollpane for
jtables and was about to use it too, but i got
confused because of the headers when i tried to see
whether the data in the table was right.You're welcome. The JTableHeaders object can be displayed in, say,
the NORTH part of a BorderLayout while the JTable itself is displayed
int the CENTER part. You can even display the headers SOUTH of
the table itself if you like. A JTable object is quite flexible.
kind regards,
Jos
