怎么把.txt文件内容导入jtable
怎么把.txt文件内容导入jtable

思路是什么？最好有个例子

------解决方案--------------------
主要就是两步
1。通过io读txt文件，可以是一行一行的读
2。将读到的数据放到jtable的指定的cell里

基本上遍历一遍txt文件或遍历一遍jtable的cell就可以了
------解决方案--------------------
这个应该可以构造一个vector的吧，每读一行的数据用vector来接收，再放在第一个vector中，应该可以的，不过如果数据量大，最好还是一行一行处理。

可以用modal.add来新增table中的行
