java设置表格的高度宽度.doc

技术关键：JTable控件用来显示和编辑常规的二维单元表。JTable有很多用来自定义其呈现和编辑的工具，同时提供了这些功能的默认设置。从而可以轻松地设置简单表。public void setRowHeight(int rowHeight)行高对于表头来讲这个方法不行。需要用到getTableHeader()方法package com.swing02;import java.awt.BorderLayout;import java.awt.Dimension;import java.awt.EventQueue;import java.awt.Font;import java.awt.GridLayout;import java.awt.event.WindowAdapter;import java.awt.event.WindowEvent;import javax.swing.JFrame;import javax.swing.JLabel;import javax.swing.JPanel;import javax.swing.JScrollPane;import javax.swing.JTable;import javax.swing.SwingConstants;import javax.swing.border.EmptyBorder;import javax.swing.table.DefaultTableModel;import javax.swing.table.JTableHeader;import javax.swing.UIManager;public class ResizeTableTest extends JFrame private static final long serialVersionUID = 6589584750853602612L; /面板容器 private JPanel contentPane; /表格 private JTable table1; /表格 private JTable table2; public static void main(String args) try /皮肤 UIManager.setLookAndFeel(com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel); catch (Throwable e) e.printStackTrace(); EventQueue.invokeLater(new Runnable() public void run() try ResizeTableTest frame = new ResizeTableTest(); frame.setVisible(true); catch (Exception e) e.printStackTrace(); ); public ResizeTableTest() addWindowListener(new WindowAdapter() Override public void windowActivated(WindowEvent e) do_this_windowActivated(e); ); /标题 setTitle(设置表格的宽度与高度); /关闭 setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); /大小及位置 setBounds(100, 100, 450, 300); /面板容器 contentPane = new JPanel(); /面板容器边框 contentPane.setBorder(new EmptyBorder(5, 5, 5, 5); /添加面板容器边框 setContentPane(contentPane); /面板容器布局格式 contentPane.setLayout(new GridLayout(1, 2, 5, 5); /面板 JPanel panel1 = new JPanel(); /添加面板 contentPane.add(panel1); /面板布局格式 panel1.setLayout(new BorderLayout(0, 0); /标签 JLabel label1 = new JLabel(默认表格); /标签内容水平居中 label1.setHorizontalAlignment(SwingConstants.CENTER); /标签字体 label1.setFont(new Font(微软雅黑, Font.PLAIN, 16); /面板添加标签 panel1.add(label1, BorderLayout.NORTH); /滚动条 JScrollPane scrollPane1 = new JScrollPane(); /滚动条 panel1.add(scrollPane1, BorderLayout.CENTER); /表格 table1 = new JTable(); /滚动条添加表格 scrollPane1.setViewportView(table1); /面板2 JPanel panel2 = new JPanel(); /容器添加面板 contentPane.add(panel2); /面板2布局格式 panel2.setLayout(new BorderLayout(0, 0); /标签 JLabel label2 = new JLabel(自定义表格); /标签对齐方式 label2.setHorizontalAlignment(SwingConstants.CENTER); /标签字体 label2.setFont(new Font(微软雅黑, Font.PLAIN, 16); /面板添加标签 panel2.add(label2, BorderLayout.NORTH); /滚动条 JScrollPane scrollPane2 = new JScrollPane(); /添加滚动条 panel2.add(scrollPane2, BorderLayout.CENTER); /表格2 table2 = new JTable(); /表格字体 table2.setFont(new Font(微软雅黑, Font.PLAIN, 14); /表格行高 table2.setRowHeight(35); /构造 JTableHeader，使用 cm 作为列模型对其进行初始化。 / table2.getTableHeader() 返回此 JTable 所使用的 tableHeader JTableHeader header = table2.getTableHeader(); /设置字体 header.setFont(new Font(微软雅黑, Font.PLAIN, 16); /设置表头的高度 header.setPreferredSize(new Dimension(header.getWidth(), 40); /显示表 scrollPane2.setViewportView(table2); protected void do_this_windowActivated(WindowEvent e) /表格模型 DefaultTableModel model = new DefaultTableModel(); /将表格模型中的数据清空 model.setRowCount(0); /设置表头 model.setColumnIdentifiers(new Object 排名, 语言 )
