How to modify the width of columns in a JTable?

I'm looking for a way to change the width of the columns of my Jtable. For the design I use a graphical tool, but I don't find the corresponding option.

This is the construction to do it from the Code: JTable.getColumnModel().getColumn(0).setPreferredWidth(100);

If you have an X table, you have to define all of them as JTable needs to have the sizes of all of them to function.

TableColumnModel columnModel = table.getColumnModel();

    columnModel.getColumn(0).setPreferredWidth(50);
    columnModel.getColumn(1).setPreferredWidth(150);
    columnModel.getColumn(2).setPreferredWidth(200);
    columnModel.getColumn(3).setPreferredWidth(250);

Select the column to which we want to set the width.
change the value " Pref. Width " to the width we want.
