I think this is what I am puzzling over. Reading code in transcribe_math.c I find nothing specific for processing tables.
By the time we are in doAlignColumns/utd_doAlignColumns in transcriber.c it seems like one is dealing with a processed linear text format rather than XML.
I have just realised why this is not quite matching up, its the semantic action file defining the escape sequences for end column and end row which doAlignColumns is using. So may be there is no table handling code in transcribe_math.c for processing table XML.
So this means that probably counting rows and columns can only occur in doAlignColumns/utd_doAlignColumns, but by that point all information like columnspan and rowspan will be lost. Also is it possible to raise an error to stop translation at that point?
I could insert some custom code in transcribe_math.c to inspect the XML structure, but then that really will be embedding document structure knowledge in the code. At the moment only MathML is used for math in LibLouisUTDML, but there is no real reason to restrict ourselves to that (eg. Office Math ML as found in newer versions of word's docx XML format).
I think we are going to have to choose the least evil option here, as things stand there seems no really good way to do it. Any thoughts?

The place to detect errors would be in transcribe_math.c .

My guess based on other function names is that utd_doAlignColumns will be for UTD output formatting where as doAlignColumns is probably for other outputs. More of a case why I say that might not be the place to provide a fix as it would need applying in multiple places.

My feeling though looking at that, it may not be the best place to fix LibLouisUTDML, it probably should be done whilst processing the XML and that function does not seem to be dealing with the XML.

I want to adjust LibLouisUTDML so that in a mtable should the number of mtd differ then it will raise an error inline with the MathML 2.0 standard.
