How to properly set column widths in Swing?

Question

Java

Good day.

I am studying an example of a table in Swing, and the following question arose:



The table is presented as a DefaultTableModel object, however, an attempt to set the width of the columns: did not lead to success, and the import required for these methods:

infoTable.getColumn(1).setPreferredWidth(150);

import javax.swing.table.TableModel;
import javax.swing.table.TableColumnModel;

ended with the message 'unused import'.

What is the correct way to set the column widths?

Thanks to.

Answer 1

TOB BOT , thank you very much.
I finally found a working version - precisely through the mvc model.

infoTableModel.getColumnModel().getColumn(0).setPreferredWidth(150);

Answer 2

setting the width is done through the ColumnModel.

for (int i = 0; i <table.getColumnCount(); i++) {
    table.getColumnModel().getColumn(i).setMinWidth(20);
    table.getColumnModel().getColumn(i).setMaxWidth(600);
}
