> According to latest OOXML standard ECMA-376 5th edition Part 1 (released on
> December 2016), Cell Reference (18.18.7, ST_CellRef) property on a Cell
> (18.3.1.4, CT_Cell) is optional.
> Actually, we believe an abandoned pull request was supposed to fix this issue
> and it wasn’t merged eventually:
> [https://github.com/apache/tika/pull/214/commits/d79aa3baf33d4f859e4daa8ef251721f3ac2a198.]
> Look at the safety block commented with:
> {code:java}
> // gracefully handle missing CellRef here in a similar way as XSSFCell
> does{code}
