问题描述

java GridBagLayout 表格内容不显示，，而且会自动居中

1. 如果不用JScrollPane，布局正常，但是不显示表头```package com.haiersoft.jxc.kcgl.view;

import java.awt.FlowLayout;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.Insets;

import javax.swing.JComponent;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.JTextField;
import javax.swing.table.DefaultTableModel;

public class KuCunPanDianPanel extends JPanel{
private JTextField pandianyuan;
private JTextField pandianshijian;
private JTextField pinzhongshu;

//private DefaultTableModel model = new DefaultTableModel();//private JTable table = new JTable(model);private JScrollPane sp_table;public KuCunPanDianPanel(){    super();    setBounds(10 10 460 300);    setLayout(new GridBagLayout());    setVisible(true);    setupComponet(new JLabel("" 盘 点 员："") 0 0 1 0 false);    pandianyuan = new JTextField(""Tsoft"");    // 定位盘点员文本框    setupComponet(pandianyuan 1 0 1 100 true);    setupComponet(new JLabel("" 盘点时间："") 2 0 1 0 false);    pandianshijian = new JTextField(""2010-5-18 16:40:41"");    // ·定位盘点时间文本框    setupComponet(pandianshijian 3 0 1 150 true);    setupComponet(new JLabel("" 品 种 数："") 4 0 1 0 false);    pinzhongshu = new JTextField(""1"");    // 定位品种数文本框    setupComponet(pinzhongshu 5 0 1 100 true);    String[] name={""商品名称""商品编号""供应商""产地""单位""规格""单价""数量""包装""};    //String[] columnNames = {""Product""Number of Boxes""Price""};    //Object data[][] = {{ ""小芳""142321"" }{ ""小芳""142321"" } };    Object[][] data =        {                            {""计算机""sp1001""小公司""山东青岛""台"""new Double(10000.000) new Integer(10)箱""}                   };    JTable table = new JTable(dataname);    //table.setPreferredScrollableViewportSize(new Dimension(300 80));  //创建一个滚动面板，包含表格    sp_table = new JScrollPane(table);    setupComponet(sp_table 0 1 10 400 true);}private void setupComponet(JComponent component int gridx int gridy        int gridwidth int ipadx boolean fill) {    final GridBagConstraints gridBagConstrains = new GridBagConstraints();    gridBagConstrains.gridx = gridx;    gridBagConstrains.gridy = gridy;    gridBagConstrains.insets = new Insets(5 1 3 1);    if (gridwidth > 1)        gridBagConstrains.gridwidth = gridwidth;    if (ipadx > 0)        gridBagConstrains.ipadx = ipadx;    if (fill)        gridBagConstrains.fill = GridBagConstraints.HORIZONTAL;    add(component gridBagConstrains);}

public void initComboBox() {

}

}

解决方案

用这个布局不行吧，你可以换个布局试试，分成两部分，盘点员那部分用flowlayout，整体使用borderlayout，你试试看
