这个Tag是string类型的。没有特别规定长度限制
文档上说
The tag is only for the application's use; the spreadsheet does not use this information in working with the data. The information in the tag is stored separately from the information provided in the text or the value or the note.
You can assign user-defined information to any cell, column, row, sheet, or the entire component. The information in the tag is not composited from these different levels. |
