怎样让JTable中的数据居中对齐?

[yujialin]

JTable默认的是左对齐，怎样让它居中对齐？

老紫竹的代码你就信了吧。DefaultTableCellRenderer其实就是一个JLabel，所以用setHorizontalAlignment(SwingConstants.CENTER)设为水平居中;

我只提供一个可运行的样例，剩下的你自己分析吧！

import java.awt.Component;

import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.SwingConstants;
import javax.swing.table.DefaultTableCellRenderer;
import javax.swing.table.TableCellRenderer;

public class MyJTable extends JTable {
  private MyCellRenderer renderer;

  public MyJTable(MyCellRenderer renderer) {
    super(8, 6);
    this.renderer = renderer;
  }

  public TableCellRenderer getCellRenderer(int row, int column) {
    return renderer;
  }

  public static void main(String[] args) {
    MyJTable t = new MyJTable(new MyCellRenderer());
    JScrollPane pane1 = new JScrollPane(t);// 
    JFrame frame = new JFrame("JTableDemo");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setContentPane(pane1);
    frame.pack();
    frame.setVisible(true);

  }
}

class MyCellRenderer extends DefaultTableCellRenderer {

  public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row,
      int column) {
    super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
    setHorizontalAlignment(SwingConstants.CENTER);
    return this;
  }
}
