How to change JTable column header text

Question

How do you set the text in the JTable column headers? I know you can create a JTable specifying the text in an array:
<li>JTable(Object[][] rowData, Object[] columnNames)
But if you create the JTable specifying a TableModel,
<li>JTable(TableModel dm)
the header text defaults to "A", "B", "C", etc. I cannot figure out how to access the text in the header names so it can be changed to something useful. I know how to get the JTableHeader for the table, but it does not seem to have methods for actually setting header values.

Answer 1

I'm sure that model allows you to specify header values so you don't have to do so manually. I would be very surprised if it didn't override the default getColumnName() method to provide a reasonable names.She wasn't writing the class, but [url http://forums.oracle.com/forums/thread.jspa?messageID=9200751#9200751]outlining a design for me to implement. And, based on a previous comment I had made, I think she assumed I wanted the new design to look as much like the old as possible. There were no headers in the original design, which wasn't even a table.
Anyway, this works:
    final static String statisticsColumnNames[] = {
     "Type", "Count",
     "Red QE", "Green QE", "Blue QE", "Average QE",
     "Distance"
     qErrors = new QEBeanTableModel();
     JTable errorTable = new JTable(qErrors);
     TableColumnModel tcm = errorTable.getColumnModel();
     for (int col = 0; col < statisticsColumnNames.length; col++)
         tcm.getColumn(col).setHeaderValue(statisticsColumnNames[col]);
It looks like setHeaderValue() on the TableColumn is what I was looking for.Again, only used if you are dynamically changing the values at run time or you don't like the defaults provided by the Bean-aware model.I coded the above before I read your last post. The QEBeanTableModel is extremely specific to my program. I.e. I cannot imagine it being used anywhere else. Would it still be better to implement a getColumnName() within the table model? Looking at your [url http://www.camick.com/java/source/RowTableModel.java]RowTableModel.java source, I can see that it would not be difficult to do so.
Just decided to add the getColumnName() method. This whole sub-project is based on implementing a clean modern design (and learning about Java Beans). You've clearly stated twice that the method I have implemented is for dynamic header values only, which has already answered what I asked last paragraph.
