What's the difference between <c t=“str”> and <c><is> in Office Open XML?
问题 What's the difference between these two Office Open XML fragments? <c r="A2" t="str"> <v>btyler</v> </c> and <c r="B2"> <is><t>btyler</t></is> </c> note: The second sample I created manually based on the spec, the first is from an actual Excel workbook. Both seem valid and pretty much identical according to the spec, so I'm wondering why there is t="str" when <is> seemingly does the same thing. When does Excel choose to use one over the other? 回答1: According to the documentation at 18.18.11
