我有一个带有复选框的表格。我想在单击第三列或第四列中的复选框时更改第一列中复选框的选择。我希望能够更改同一行中的其他单元格。我已经有了列，所以我想知道单元格在哪一行。我也很不确定到目前为止我是否正确。

到目前为止，我所做的主要是从

最佳答案

差不多了

在调用commitEdit之前，需要先调用getTableView().edit(getTableRow().getIndex(), param)。这会将单元格置于“编辑模式”。由于没有 startEdit 方法，因此进入编辑模式涉及的内容很少，但仍然是必需的。

之后，如下所述:http://download.oracle.com/javafx/2.0/ui_controls/table-view.htm

需要调用

firstCol.setOnEditCommit(new EventHandler<EditEvent<String>>() {
    @Override
    public void handle(EditEvent<String> event) {
        String newValue = event.getNewValue();
        ContactOptions data = (ContactOptions) event.getTableView().getItems().get(event.getTablePosition().getRow());
        data.one.set(newValue)
        if(newValue.equals("No")) {
            data.three.set("No");
            data.four.set("No");
        }
    }
}

现在我只需要知道 how to update the table's display once the data is updated .
