Question

我有一个JTable有3列，第二列有ImageIcon个。我想仅通过图像的名称来过滤该列，但是存在一个问题：该列的内容是图像的完整路径，如果我输入路径中的单词/字母，我会收到所有记录

例如

这是我的jTabel getColumnClass： enter image description here

并且没有getColumnClass： enter image description here

如果我输入＆＃34;资源＆＃34;在Enter value字段中没有任何变化，因为所有单元格都有此内容。

是否有任何方法只能通过没有扩展名的图像名称进行过滤（例如橙色，沃达丰，cosmote）？

以下是我的代码：

也许您可以在要过滤的正则表达式中包含路径？像：

String path = "resources\/opIcons\/";
RowFilter.regexFilter("^"+path+".*"+filterValue+".*$", sortColumn)

通过ImageIcon列过滤jTable
