Java GridLayout布局panel

布局一个panel，部分源码如下：
private JPanel getDataFieldsPanel(ArrayList<DataField> dataFields) {


// create panel to hold labels and textFields
JPanel displayPanel = new JPanel();

//set the layout of the display panel

displayPanel.setLayout(new GridLayout(dataFields.size(), 2, 0, 0));
//displayPanel.makeColumnsEqualWidth = false;

// create the components according to the length of dataFields
for(DataField element : dataFields) {

JLabel nameLabel = new JLabel(element.getName() + ":");
displayPanel.add(BorderLayout.WEST, nameLabel);

JTextField valueField = new JTextField(element.getValue(), 10);
valueField.setEditable(false);
displayPanel.add(valueField);
}

return displayPanel;

}
效果如图,

结果是两列组件的等宽，问题就是两列内容离得太远了，想靠近一点儿，怎么解决？
