JTable column headers not showing up

Question

I have a JTable inside a JScrollPane which, in turn, is inside a JTabbedPane.
I created a TableModel which extends AbstractTableModel as per the java Swing Tutorial examples.
In that model is an Object[][] object for the data called rowData, and all the data displays in the table perfectly.
I also have a String[] object called columnNames to define the column headers. ..the column names are coded directly into the object.
i.e.: String[] columnNames = {"John", "Janet", "Jamie", "Jennifer"};But the column names don't display at all.....all I get in the column headers is 'A', 'B', 'C', etc.
I need to know either
1)how to set this up correctly in the first place or
2)how I can reset the columns manually.
I have tried adding the table 2 ways..as follows...but neither one gets the headers right:
JScrollPane jScrollPane = new javax.swing.JScrollPane(getTable());or
JScrollPane jScrollPane.setViewportView(getTable());Note: getTable()..is where the new javax.swing.JTabel(new TableModel())stuff is done.
thx, ESW

Answer 1

You mentioned the you columnNames array. I suggest you declare it as static and accessible from within your custom table modelprivate static final String[] COLUMN_NAMES = {"John", "Janet", "Jamie", "Jennifer"};Then you override/implement the following methods in your TableModel :public String getColumnName(int column) {
     return COLUMN_NAMES[column];
public int getColumnCount() {
     return COLUMN_NAMES.length;
}That should do the trick.
