使用工作版本解决和编辑并留下以防万一它可以帮助其他人
此 jTable 的行是从 2D 字符串数组中填充的。该数组将是动态的。我只需要显示 10 行 3 秒，然后再显示 10 行 3 秒，重复此循环直到数组结束，然后重新填充数组并再次开始循环。
我找不到任何使用时间延迟来更新表而不是按钮、数据更改等的 jTables 示例。
编辑- 修复了使用 Timer ActionListener 显示的行
要显示的行也将从 jSpinner 中选择，但是如何实现设置行而不是显示所有行？jScrollPane 中禁用了垂直和水平滚动。
编辑- 我仍然坚持如何“重新填充”并在第一次显示我的数组 1 中的所有记录后显示新记录..用另一个 Timer/ActionListener 和新的 DefaultTableModel 解决
