Filter JTable only one one column
提问by CMP
I have a JTable and I would like to do a filter from a JTextfieldbut only filter the results based on one column and not to search all columns.
我有一个 JTable，我想从 a 进行过滤，JTextfield但只过滤基于一列的结果而不是搜索所有列。
I have my JTable I can filter but my filter will filter and search every column of the table I want to restrict it to one column

listen to changes in the textFields document and set the appropriate rowFilter limited to the column you want to filter:
聆听 textFields 文档中的更改，并将适当的 rowFilter 设置为限制为您要过滤的列：
// on document change
RowFilter rowFilter = RowFilter.regexFilter(textField.getText(), myColumn);
table.getRowSorter().setRowFilter(rowFilter);
(type-cast and guard against empty textfield ommitted)
（类型转换和防止空文本字段被忽略）

Keep a master copy of all the rows (or supporting data) in the background.
在后台保留所有行（或支持数据）的主副本。
When searching, take the search criteria from the text field and rebuild the table model by only adding items that match the criteria. If the text field is empty then add all rows.
搜索时，从文本字段中获取搜索条件并通过仅添加符合条件的项目来重建表模型。如果文本字段为空，则添加所有行。
