Hello! I need to alter a TableModel . More exactly I need to remove some columns from it and later add some. I tried this working both on the table ( JdbTable ) and the TableColumnModel but the TableModel didn't change. If nobody can help me on this, then please tell me how can I get a TableModel from a QueryDataSet object. I tried this: myJdbTable.setDataSet(objQueryDataSet) , but all I get from the TableModel of myJdbTable is 1 column named A . Please help! Thank you!    More>>
