could not set the column width to zero i.e. not made column invisible
not, never to remove
TableColumn
fromTableModel
, this is wrong suggestion, instead of to use built-in method JTable#removeColumn(TableColumn aColumn),notice, this method remove column only from View, in the model is removed column still presents, and you can revert that, visible the removed column by using JTable#addColumn(TableColumn aColumn)

EDIT2
you have to check too
JTable.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
JTable.getTableHeader().setReorderingAllowed(false);
If it should be removed, and not just hidden: Remove it from the table-model. If it only should be hidden and later shown, you can remove the TableColumn from the TableColumnModel
Making the column height 0 is a bit bogus.
