setPreferredWidth() for table column display incorrectly

I have a table like this image, That doesn't contain any data

enter image description here

So i want remove spaces after Send column, And i'am using

table.getColumnModel().getColumn(0).setPreferredWidth(5);   //first column size
System.out.println(table.getColumnModel().getColumn(0).getPreferredWidth());

But it prints 15 !!
if i set the setPreferredWidth to a number that be greater than 15 it affects the column
but if i set the setPreferredWidth to a number that be smaller than 15 it doesn't affect the column, and it takes 15 by default

how can i solve it?

Use setMaxWidth(int) to define not only prefered size but also max one, in your case

table.getColumnModel().getColumn(0).setPreferredWidth(5);
table.getColumnModel().getColumn(0).setMaxWidth(5);
System.out.println(table.getColumnModel().getColumn(0).getPreferredWidth());

OUTPUT: 

5
