java - How to add column with header and data to the JTable

Question

I created a class MyTableModel which extends AbstractTableModel. And what I want is, to have already initialized three columns with data? Only with DefaultTableModel I had that option, that I could use a method that takes as a paramater columnName and columnData addColumn(Object columnName, Object[] columnData), so what's the best way to do this?

Answer 1

在您的表格模型中，您可以让它返回您想要的任何内容。如果您有三个List<String>或一个List<ThreePropertyPojo>，则表模型方法可以正确回答：

1. 列数为 3
2. 行数是list.size()
3. 显示使用的单元格 (row,col) 的值list1.get(row)（或 2 和 3，取决于“col”）或取决于“col”的值，您可以从列表元素中获取特定属性。

这几乎可以做到。

如果你谷歌“java swing tablemodel example”有很多例子
