Java Swing - 如何获取/设置JTable中单元格之间的间隙大小

 
import java.awt.Dimension;

import javax.swing.JTable;

public class Main {
  public static void main(String[] argv) throws Exception {

    JTable table = new JTable();

    Dimension d = table.getIntercellSpacing();
    // d.width == 1, d.height == 1

    //Add 5 spaces to the left and right sides of a cell

    int gapWidth = 10;
    int gapHeight = 4;
    table.setIntercellSpacing(new Dimension(gapWidth, gapHeight));
  }
}
