I have a JTable that stores the results of a database query, so far so good. What I want is for the last column in each table to have a clickible JButton that will open the edit screen for the object represented in that row, and that means the button will need to know the details of the first column in the table from its own row (the ID from the database).
我有一个存储数据库查询结果的JTable，到目前为止一直很好。我想要的是每个表中的最后一列有一个可点击的JButton，它将打开该行中表示的对象的编辑屏幕，这意味着该按钮需要知道表中第一列的详细信息拥有行（数据库中的ID）。
Any advice? I already tried just adding JButtons but they turned into Text when I tried to run it.
任何建议？我已经尝试过添加JButton，但是当我尝试运行它时它们变成了Text。

Contrary to the tutorial above, there is a way to do this without a complicated positioning math, custom mouse listeners, and custom table models. Instead, it can be done with a single simple custom class following the pattern described here:

Take a look at Sun's introduction to the JTable component, specifically, the section about Editors and Renderers. It discusses the use of alternative CellRenderers, and CellEditors. What you'd need to do is create (or borrow) a ButtonCellRenderer and a ButtonCellEditor and then apply them to the column in question in your JTable. The examples found in the linked articles should give you all the information you need.
