JTable hide and show columns

Question

I want to add some columns to a table (Swing JTable). Some of them will have a default size (e.g. 250), others will be hidden (so their size will be 0). I use this code:

Answer 1

I think you have named your methods incorrectly, when you want to hide a column you will set

column.setMinWidth(0);
column.setMaxWidth(0);
column.setPreferredWidth(0);

but in your code you are doing this when you want to show a column which is exactly opposite.

Also there is no need to call this "setWidth" method on a TableColumn, read TableColumn#setWidth(int).
