How to reset JTable header

252 Contributor
I am setting the JTable header using setModel() method. Before that I am setting method setAutoCreateColumnsFromModel(boolean) to false. After this I want to change the column header names for localization. But method setAutoCreateColumnsFromModel(boolean) is not allowing to change the column headers, If I change it to true then it changes the layout of the table.

Please suggest any way to change the column header names without changing the layout.

Thanks in advance.

Given the table get the TableColumnModel; given that object get the TableColumns and use the setHeaderValue() method to set the new column headers.

kind regards,

I tried your suggestions, it solved the problem but when I added the new data using addColumn() method. ... it added two new columns in the Jtable but I want to replace the existing columns with the new columns and I am not able to find the way to do it ... Please suggest ?

thanks and regards,

That is an entirely different problem; you can only append or remove columns; you can't directly replace them. Better install an entirely new TableModel.

kind regards,

Hi all. I've defined a custom TableModel so I can use custom types for my JTable. However, because of this, the table's TableColumnModel is totally out of sync with the model (ie. it isn't populated with any column data at all. No TableColumns or anything). This is annoying, since I need some reference to TableColumn objects (to do some column...
