The approach described above is sufficient to parse most Wiktionary data, but a large percentage of Wiktionary inflection tables do not use the correct tags to distinguish between header and content cells, an important component of the parsing procedure.
table authors frequently use only the content cell tag to mark up all of a table's cells, and create "soft" headers with a distinct visual appearance by changing their styling (as with Czech verbs, such as spadat 'to be included, fall off').
