The sprms that state one border set for a whole row or table and cascade it down to the cells (sprmTTableBorders, sprmTSetShdTable, sprmTCellShdStyle) are not read, so a table formatted the common way converts with zero borders rather than approximated ones. This is a visibly wrong output rather than a subtle fidelity loss, and it affects the most ordinary shape of a Word table. Separately, style-inherited formatting is dropped, so a Heading 1 paragraph reports its styleId but not the boldness or size the style would supply.

README: "the sprms that state one border set for a whole row or table and cascade it down to the cells ... are not [read]. ... a table whose borders are stated only that way reads with no cell borders at all rather than with approximated ones"; and "A Heading 1 paragraph reports its styleId and headingLevel but not the boldness or size its style would supply."
