jtable小例子 实现jtable的功能

package com.lovo.study;

import javax.swing.table.AbstractTableModel;

public class DataTable extends AbstractTableModel {

	public String[] title;

	public Object[][] data;

	public DataTable(String[] title, Object[][] data) {
		this.title = title;
		this.data = data;
	}

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

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

	public Object getValueAt(int rowIndex, int columnIndex) {
		return data[rowIndex][columnIndex];
	}

	// 设置标题方法
	public String getColumnName(int col) {
		return title[col];
	}

	// 设置辨别数据类型的方法(如boolean类型显示为复选框)
	public Class getColumnClass(int c) {
		return getValueAt(0, c).getClass();
	}

	//设置表格是否可以编辑
	public boolean isCellEditable(int rowIndex, int columnIndex) {
		return true;
	}
	
	//设置表格单元格是否可以接受输入值
	public void setValueAt(Object val,int row,int col){
        data[row][col]=val;
        fireTableDataChanged();
     }
