The current MathML implementation recognizes and parses row and column attributes (e.g. rowalign, columnalign, rowlines, and columnlines) that are set on <mtable>, <mtr>, and <mtd> elements, but it does not parse them when they are set on <mstyle> and <math> elements.
nsMathMLmtdFrame::GetRowSpan and nsMathMLmtdFrame::GetColSpan call mContent->GetAttr instead of GetAttribute so I suspect this bug applies to mtd@rowspan and mtd@colspan too.
mtable@frame is implemented in mathml.css and so the attributes on mstyle or math are not taken into account.
Summary: Row and column attributes not parsed from <mstyle>/<math> elements → Some tabular attributes not parsed from <mstyle>/<math> elements
