100分求JTable解决方案
我想在表格中加入一个控件，比如说进度条.图片,按钮.但是表格中只显示这个进度条的相关属性,并不把这些控件显示出来,请较高手.代码方式表述.

需要实现接口TableCellRenderer，即提供一个单元格绘制器，用于绘制如JButton
然后table.setDefaultRenderer()设置绘制器
给你一个很简单的例子

package csdn;

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

//实现TableCellRenderer，绘制JButton
class JTableButtonRenderer extends JButton implements TableCellRenderer {
private TableCellRenderer defaultRenderer;

public JTableButtonRenderer(TableCellRenderer renderer) {
defaultRenderer = renderer;
}

public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected,
boolean hasFocus,
int row, int column)
{
if (isSelected) {
this.setBorder(BorderFactory.createLineBorder(Color.BLUE));
}
else {
this.setBorder(null);
}
return this;
}
}

class JTableButtonModel extends AbstractTableModel {
private Object[][] rows = {{new JButton( "test ")}};
private String[] columns = { "test "};

public String getColumnName(int column) {
return columns[column];
}

public int getRowCount() {
return rows.length;
}

public int getColumnCount() {
return columns.length;
}

public Object getValueAt(int row, int column) {
return rows[row][column];
}

public boolean isCellEditable(int row, int column) {
return false;
}

public Class getColumnClass(int column) {
return getValueAt(0, column).getClass();
}
}


public final class TableTest extends JFrame {
private JTable table;

public TableTest() {
TableCellRenderer defaultRenderer;

table = new JTable(new JTableButtonModel());
defaultRenderer = table.getDefaultRenderer(JButton.class);
table.setDefaultRenderer(JButton.class, new JTableButtonRenderer(defaultRenderer)); //设置绘制器
table.setPreferredScrollableViewportSize(new Dimension(400, 200));
this.setContentPane(table);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setSize(300, 300);
}

public static void main(String[] args) {
JFrame frame = new TableTest();
frame.setVisible(true);
}
}

表格重绘时，才能看得到

this.setSize(489, 253);

this.setContentPane(getJContentPane());
this.setTitle( "JFrame ");


}

}

}

public class TableProcessRender implements TableCellRenderer

public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column)

}

}

上面第二个程序的getXX()方法没有被周用,就实现上述功能了,请问之间是怎样的一种关系?希望能够具体点
[解决办法]
仔细看，调用了
Constructor MainFrame() --> initialize() --> getJContentPane() --> getXX()
[解决办法]
不好意思,开始没有看清楚,我把上面的empireconquer的代码运行了下,里面还有一个问题,就是里面所有的进度条都是一个值,请问,怎样实现多个进度条的不同值显示?
