表格？

[afdzhu]

在swing 里，请问如何让表格的每一列，不是默认的大小，可以根据自己的设置来，显示啊？

TableColumn column = jtable.getColumnModel().getColumn(1);
column.setPreferredWidth(20);
类似于这样

[shengli_liao]

jTable.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);

import javax.swing.*;
import javax.swing.table.*;
import java.awt.*;
import java.util.*;

public class SimpleTable extends JFrame {
public SimpleTable() {

Vector cell ;
Vector row = new Vector();
DefaultTableModel tableModel = new DefaultTableModel();
String[] tableHeads = {"ID","姓名", "年龄", "城市"};
Vector tableHeadName = new Vector();
for (int i = 0; i < tableHeads.length; i++) {
tableHeadName.add(tableHeads[i]);
}
for (int i = 1; i <= 100; i++) {
cell = new Vector();
cell.add(i);
cell.add("曹操"+i);
cell.add("");
cell.add("");
row.add(cell);
}

tableModel.setDataVector(row, tableHeadName);

JTable table = new JTable(tableModel);
TableColumn column;
column=table.getColumnModel().getColumn(0);
column.setPreferredWidth(12);
table.setRowHeight(20);

JScrollPane scrollPane = new JScrollPane(table);
scrollPane.setCursor(new Cursor(12));
this.getContentPane().add(scrollPane);
this.setTitle("使用JTable表格的例子");
this.setSize(300, 300);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setVisible(true);
}


public static void main(String[] args) {
SimpleTable test = new SimpleTable();
}
}

请问是把 jtble 放入 jScrollPane中嘛？我按楼上楼上
TableColumn column = jtable.getColumnModel().getColumn(1);
column.setPreferredWidth(20);
怎么下面没有滚动条啊？
