JTable how to hide column in view but keep it in model for use it in background

Question

I have a JTable and am passing a data array into the TableModel. I wish to retain all columns in the data model as I need them all for background data processing, but I wish to show only some of the columns in the JTable.

How do I achieve this -- to remove a data column from the view (the visualized JTable) but not from the model (the TableModel)?

How to remove a column has been answered, however a better solution would be to create your own table model which provides the table with the relevant data. — vickirk, Jul 28 '11 at 07:45
You can hide columns dynamically, as shown [here](http://stackoverflow.com/questions/6793257/add-column-to-exiting-tablemodel/6796673#6796673) and [here](http://stackoverflow.com/questions/6793257/add-column-to-exiting-tablemodel/6798013#6798013). — trashgod, Jul 28 '11 at 08:09

I know remove column method. My doubt is how will it arrange data in columns. Say I have 3 columns. I have model data of 3 columns. I want to show only 2 columns. So how will it recognize which data to put in which column? – Umesh K Jul 28 '11 at 07:47

Override getColumnCount of the model to return less columns that there is. Then put your hidden columns as last columns of the model.
