JTable setPreferredWidth causing an extra column

This is my code

JTable table = new JTable(attributeValues, attributeNamesString);

table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);

for(int z=0;z<table.getColumnCount();z++){
    table.getColumnModel().getColumn(z).setMinWidth(100);
    table.getColumnModel().getColumn(z).setMaxWidth(100);
    table.getColumnModel().getColumn(z).setPreferredWidth(100);
}

Unfortunately, when I run this, I get an additional column on the screen which stretches to the window size. I'm not sure where it's come from or how to fix it.

Are you sure this is caused by the table.getColumnModel().getColumn(z).setPreferredWidth(100); call? I suspect (although I haven't tried it myself) that it is more likely caused by table.getColumnModel().getColumn(z).setMaxWidth(100);, as this sets the columns' maximum width (adding up to 4 x 100px in your case) while the table itself is stretched to more than 4 x 100px.

If you do not want the table itself to be wider than 4 x 100px, can you not set the maximum size of the table as well (http://docs.oracle.com/javase/7/docs/api/javax/swing/JComponent.html#setMaximumSize(java.awt.Dimension))?
