-这样会给表格增加一列排序列，拖动之后在表格顶部会出现一个Save order的按钮，点击保存排序
+This will add a column to the grid. After dragging one row, a `Save order` button will appear at the top of the grid. Click  to save order.
 
 ## Translation
 
-排序保存按钮默认的文字是`Save order`，如果使用其他语言，比如简体中文，那么可以在`resources/lang/zh-CN.json`文件中增加一项翻译
+The default text for the button is `Save order`. If you use an other language, such as Simplified Chinese, you can add a translation to the `resources/lang/zh-CN.json` file.
