There is a reference to this.colspan there, but it should be this.colSpan and it causes the used colspan to always be 1. This might have some effect on the format detection or something, but I couldn't readily find a testcase that would illustrate that this error has any effect. Requires further investigation.

So no. I just noticed it when I copied that code and rewrote it for rowspan only to figure out that the code block wasn't working. I tried finding what would be broken due to this, but was not able to find an issue yet. (possibly the whole block isn't even required ?)
