SWING复杂表格例子

Swing里的提供的表格过于简单。要做复杂的表格得花一番功夫。现把以前做过的整理如下：

1. 表格里有checkbox的表格

package test;
/**
 * Another JTable example, showing how column attributes can be refined
 * even when columns have been created automatically. Here we create some
 * specialised renderers and editors as well as changing widths and colors
 * for some of the columns in the SwingSet demo table.
