有没有办法在 TableLayout 的单元格中设置对齐方式？

【解决方案1】：

这是一个使用TableLayoutConstraints的例子：

import javax.swing.JButton;
import javax.swing.JFrame;
import layout.TableLayout;
import layout.TableLayoutConstraints;

public class TableLayoutCellAlignmentExample {

    public static void main(String args[]) {

        JFrame frame = new JFrame("Example of TableLayout");
        frame.setSize(700, 400);

        double size[][] = {{200,200,200}, // Columns
            {100,100,100}}; // Rows

        frame.setLayout(new TableLayout(size));


        String[] labels = {
            "should be TOP LEFT",
            "should be TOP CENTER",
            "should be TOP RIGHT",
            "should be MIDDLE LEFT",
            "should be MIDDLE CENTER",
            "should be MIDDLE RIGHT",
            "should be BOTTOM LEFT",
            "should be BOTTOM CENTER",
            "should be BOTTOM RIGHT",
        };

        frame.add(new JButton(labels[0]), new TableLayoutConstraints(0, 0, 0, 0, TableLayout.LEFT, TableLayout.TOP));
        frame.add(new JButton(labels[1]), new TableLayoutConstraints(1, 0, 1, 0, TableLayout.CENTER, TableLayout.TOP));
        frame.add(new JButton(labels[2]), new TableLayoutConstraints(2, 0, 2, 0, TableLayout.RIGHT, TableLayout.TOP));
        frame.add(new JButton(labels[3]), new TableLayoutConstraints(0, 1, 0, 1, TableLayout.LEFT, TableLayout.CENTER));
        frame.add(new JButton(labels[4]), new TableLayoutConstraints(1, 1, 1, 1, TableLayout.CENTER, TableLayout.CENTER));
        frame.add(new JButton(labels[5]), new TableLayoutConstraints(2, 1, 2, 1, TableLayout.RIGHT, TableLayout.CENTER));
        frame.add(new JButton(labels[6]), new TableLayoutConstraints(0, 2, 0, 2, TableLayout.LEFT, TableLayout.BOTTOM));
        frame.add(new JButton(labels[7]), new TableLayoutConstraints(1, 2, 1, 2, TableLayout.CENTER, TableLayout.BOTTOM));
        frame.add(new JButton(labels[8]), new TableLayoutConstraints(2, 2, 2, 2, TableLayout.RIGHT, TableLayout.BOTTOM));

        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setVisible(true);
        frame.pack();
    }
}

结果：
