java中JTable怎么设置选中表格的其中一行，通过java语言进行选中

假设JTable table已实例化，设置选中表格中的行：

table.setRowSelectionInterval(int index0,int index1)//选择从 index0 到 index1 之间（包含两端）的行。

table.setRowSelectionInterval(0,0)//表示选中第一行

给你个简单范例：

import java.awt.BorderLayout

import java.awt.event.ActionEvent

import java.awt.event.ActionListener

import javax.swing.*

import javax.swing.table.TableModel

public class TableDemo extends JFrame {

public TableDemo() {

table = new JTable(new String[][]{{"a"}, {"b"}, {"c"}, {"d"}},

new String[]{"name"})

this.add(new JScrollPane(table))

JButton button = new JButton("search")

button.addActionListener(new ActionListener() {

@Override

public void actionPerformed(ActionEvent e) {

TableModel model = table.getModel()

for (int i = 0i <model.getRowCount()i++) {

Object value = model.getValueAt(i, 0)

if(field.getText().equals(value)){

table.setRowSelectionInterval(i, i)

return

}

}

table.clearSelection()

}

})

JPanel panel = new JPanel()

panel.add(new JLabel("key:"))

field = new JTextField(5)

panel.add(field)

panel.add(button)

this.add(panel,BorderLayout.SOUTH)

this.pack()

this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE)

}

public static void main(String[] args) {

new TableDemo().setVisible(true)

}

private JTable table

private JTextField field

}
