How to hide a particlar column in DefaultTableModel from displaying it in table?

Question

I am using Java Swingx framework. I have 4 columns in my DefaultTableModel object. I wish to display only 3 of the columns. But, I need all four for computing.<

Answer 1

No need to adjust your model, or to try to make that column very small. JTable has built-in functionality for this: the removeColumn method. As stated in the javadoc of that method

Removes aColumn from this JTable's array of columns. Note: this method does not remove the column of data from the model; it just removes the TableColumn that was responsible for displaying it.

Also note the existence of the following methods:

• JTable#convertColumnIndexToModel
• JTable#convertColumnIndexToView

Since the column order and column count in the view (the JTable) might be different from the one in the model you need those methods to switch between view and model
