Java: JTable columns don't fit in JScrollPane when scrolled horizontally
I have JTable inside JScrollPane and I am struggling with the problem, that JTable doesn't fit in JScrollPane when scrolled horizontally. I have 18 rows in JTable but only 16 rows shown when I scroll horizontally. Here is what I mean
So as you can see from the picture rows kinda run on the columns and last 2 rows are missing.
I haven't coded programatically anything yet, everything has been done using Netbeans IDE Design builder.
P.S. Interesting fact thou, if I expand my program or enter full screen, program shows ALL columns that must be there. But if I shrink program again and try to use horizontal scroll, that's what happens.
If I missed anything (sorry first time posting here) just ask. Thanks for the help!
So here is the code from the Netbeans regarding main UI window
package View;
import static javax.swing.JFrame.EXIT_ON_CLOSE;
import base.*;
import java.awt.Dimension;
/**

public class V_main extends javax.swing.JFrame {
/**
* Creates new form V_main
*/
public V_main() {
initComponents();
setDefaultCloseOperation(EXIT_ON_CLOSE);
setLocationRelativeTo(null);
Dimension d = account_table.getPreferredSize();
jScrollPane1.setPreferredSize(
new Dimension(d.width,account_table.getRowHeight()*18+1));
}

Set the header's width more bigger,for example 10000,it will solve the problem! example code below: Tablename.getTableHeader().setPreferredSize(new Dimension(10000,30));

You either can scroll or have all columns fit (squeezed if there are many) visible without scrollbar. The behaviour is controlled by the autoResizeMode property. To show the scrollbar:
table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
To show all columns, each getting the same amout of excess width:
table.setAutoResizeMode(JTable.AUTO_RESIZE_ALL_COLUMNS);
The latter is the default (modulo netbeans' interference, don't know anything about that part).
Edit
The error in this particular context seems to be calling setPreferredSize on both the table and its enclosing scrollPane with incompatible sizes. The outcome is undetermined behaviour when the actual size is bigger than the table's hard-coded pref.
Bottomline: yet another reason why you shouldn't use setXXSize on a component, ever. Here the way out is to implement the table's getPreferredScrollableViewportSize (which is part of its Scrollable role) to return something reasonable in terms of column/row sizes.
