I am using netbeans and trying to use jTable from its designer’s section. The default numbers of columns is 4. I want to make it 3 only, but as I click the columnCount it says “Custom Editing of this Property is not Supported”.
Can you help me about this problem? Thank you in advance.
Right click on table ->
Table contents...->Columnstab -> select column ->Deleteor
Right click on table ->
Table contents...->Columnstab -> decrementCount(click on the little downwards arrow)
