    Default remove a colum from a DefaultTableModel

    hi everyone, I have a DefaultTableModel that I built with tableModel.addColumn("dasdasfasfs"), thereafter I fill it with addRow.
    I want to reuse the tableModel, but before I want to clear it (rows and columns) to add different columns and different rows.

    for the rows:
    for (int i = 0; i < this.tableModel.getRowCount(); i++) {
    this.tableModel.removeRow(i);
    }

    but don't know how to remove the columns

    thanks

    There are methods that set the column identifiers (setColumnIdentifiers(...)), which replace the current identifiers. Why not just instantiate a new instance?

    ok problem solved, use setColumnIdentifiers better than addColumn, it just replace columns, thanks copeg!
