How to hide a particlar column in DefaultTableModel from displaying it in table?

Question

I am using Java Swingx framework. I have 4 columns in my DefaultTableModel object. I wish to display only 3 of the columns. But, I need all four for computing.<

Answer 1

try this to remove a single column:

myTableModel = new DefaultTableModel();
myTableModel.setColumnIdentifiers(new Object[]{"S.No.", "ID", "GDC ID", "Decsription"});
JTable myTable = new JTable(myTableModel);

// remember to save the references
TableColumn myTableColumn0 = guiLoteryNumbersTable.getColumnModel().getColumn(0);
TableColumn myTableColumn1 = guiLoteryNumbersTable.getColumnModel().getColumn(1);
TableColumn myTableColumn2 = guiLoteryNumbersTable.getColumnModel().getColumn(2);
TableColumn myTableColumn3 = guiLoteryNumbersTable.getColumnModel().getColumn(3);

myTable.getColumnModel().removeColumn(myTableColumn1);

Then to show the column again keeping the order:

// 1- remove all the existent columns
myTable.getColumnModel().removeColumn(myTableColumn0);
myTable.getColumnModel().removeColumn(myTableColumn2);
myTable.getColumnModel().removeColumn(myTableColumn3);

// 2- add all the columns again in the right order
myTable.getColumnModel().addColumn(myTableColumn0);
myTable.getColumnModel().addColumn(myTableColumn1);
myTable.getColumnModel().addColumn(myTableColumn2);
myTable.getColumnModel().addColumn(myTableColumn3);

Sorry, but that's the best way I know.
