Row root

排根───Row root

Additionally, for each row, we will return a valid XML document containing a root element only.───另外，对于每一行，返回一个有效的XML文档，其中只包含一个根元素。

A row will be created inside of the root column container for every tag that you put in your static layout file.───在您放入静态布局文件的每一个标签，都会在根列中创建一个行。

If the row isn't empty after adding cells, you can attach it to the root element at the bottom of the row loop.───如果行在添加单元格之后不为空，那么您可以在行循环的底部将它附加到根元素。
