+[w2x] The option ignore_table_dimensions has been replace by a new option table_size with values none (do not export table

+  If set to true, all tables are exported with relative width, even
+  if they have an absolute width in the source document

   text content except whitespace and an optional sequence number in brackets is considered a display equation. In that case
   it is exported with display="block"
