This problem is the same as #1238, which was resolved by #1239. For that issue, the fix was to check in one place whether $this->mapCellXfIndex[$xfIndex] was set before using it. The sample spreadsheet supplied as a description for this problem had exactly the same problem in 2 other places in the code. In addition, there were 7 other places in the code where that particular item was used unchecked. This fix corrects all 9 locations. The spreadsheet supplied with the problem is used as the basis for some new tests, which particularly test column dimensions and styles, the problems involved in this case.
