JTAble表头问题

Question

我给表头设定了自定义的绘制器后,表头的网格线不见了?有什么办法可以显示吗?
表头的绘制器用label.还就是表头的行高怎么设置?解决即给分

Answer 1

setShowGrid(boolean showGrid) 
          设置表是否绘制单元格周围的网格线。setRowHeight(int row, int rowHeight) 
          将 row 的高度设置为 rowHeight，重新验证并重新绘制它。这两个...

Answer 2

DefaultTableCellRenderer render = (DefaultTableCellRenderer) tbModules
.getTableHeader().getDefaultRenderer();
Dimension d = render.getSize();
d.height = 25;
render.setPreferredSize(d);这是表头高的设置

Answer 3

网格布局
一下是我在做图书管理系统是用的表格，可以参考一下：
final Object[] bb={"编号","条形码","名称","索书号","分类号","一级分类","二级分类","存放位置","出版社","作者","译者","数量"};//列标题   
        Object[][] rowData=new Object[32][12]; 
        table=new JTable(rowData,bb);  //实例化表格
         
        JScrollPane pane = new JScrollPane (table); 
        JPanel panel = new JPanel (new GridLayout (0, 1));//以矩形网格形式对容器的组件进行布置
        panel.setPreferredSize (new Dimension (600,400));//设置panel首选大小
        panel.setBackground (Color.black);
         
        panel.add (pane);
        panel.setBounds(0,200,880,300);
        c.add(panel);

有个tableHeader，你查下API

Answer 5

你重写了getTableCellRendererComponent方法吧?那么你只需要在这个方法最后加上
setBorder(UIManager.getBorder("TableHeader.cellBorder"));
就可以了.

Answer 6

问题解决.
setBorder(UIManager.getBorder("TableHeader.cellBorder")); 

Answer 7

还有点问题.我把代码贴出来吧.现在网格线可以显示.可是表头的行高没办法设置了.import javax.swing.*;
import java.awt.*;
import java.awt.event.*; 
import javax.swing.table.*;
public class Test extends JFrame {
public Test() {
Container contentPane = getContentPane();contentPane.setLayout(new FlowLayout());
contentPane.add(new JTable(10,10)); 
JTable t = new JTable(10,10);
headerRender render = new headerRender();
t.getTableHeader().setDefaultRenderer(render);
contentPane.add(new JScrollPane(t));}
public static void main(String args[]) {
GraphicJavaWindowHandler.launch(new Test(),
"Tables and Scrollpanes",100,100,850,700);
}
}
class GraphicJavaWindowHandler extends WindowAdapter {
public static void launch(final JFrame f, String title,
final int x, final int y, 
final int w, int h) {
f.setTitle(title);
f.setBounds(x,y,w,h);
f.setVisible(true);f.setDefaultCloseOperation(
WindowConstants.DISPOSE_ON_CLOSE);f.addWindowListener(new WindowAdapter() {
public void windowClosed(WindowEvent e) {
System.exit(0);
}
});
}
}class headerRender extends DefaultTableCellRenderer
{
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column)
{
label.setText(value.toString());
label.setBorder(UIManager.getBorder("TableHeader.cellBorder"));
Dimension d =label.getSize();
d.height = 36; 
label.setSize(d);
return label;
}
JLabel label = new JLabel();
}

第一个问题已经解决了吧？没绘制border
第二个：可以设置prefferdSizeimport java.awt.Component;
import java.awt.Container;
import java.awt.Dimension;
import java.awt.FlowLayout;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JScrollPane;
import javax.swing.JTable;

import javax.swing.WindowConstants;
import javax.swing.table.DefaultTableCellRenderer;public class Test extends JFrame {
    public Test() {
        Container contentPane = getContentPane();        contentPane.setLayout(new FlowLayout());
        contentPane.add(new JTable(10, 10));
        JTable t = new JTable(10, 10);        headerRender render = new headerRender();
        t.getTableHeader().setDefaultRenderer(render);
        t.getTableHeader().setPreferredSize(new Dimension(0, 50));
        contentPane.add(new JScrollPane(t));    }    public static void main(String args[]) {
        GraphicJavaWindowHandler.launch(new Test(), "Tables and Scrollpanes", 100, 100, 850, 700);
    }
}class GraphicJavaWindowHandler extends WindowAdapter {
    public static void launch(final JFrame f,
                              String title,
                              final int x,
                              final int y,

                System.exit(0);
            }
        });
    }
}class headerRender extends DefaultTableCellRenderer {
    public Component getTableCellRendererComponent(JTable table,
                                                   Object value,

        label.setSize(d);
        return label;
    }    JLabel label = new JLabel();
}

还有，你帖子发错区了吧？
这个算GUI设计里的
