There are a few issues with table-related markup in the spec that cause problems in Word->HTML conversion. Here are the necessary fixes in the Word document:
Above table 8, in the text "Table 8 summarises", and above table 9, in the text "Table 9 summarises", set the cursor at the end of the white space after the table number and delete backwards until the table reference is highlighted. Reinsert one white space. This deletes some empty cross references left over from previous edits.
Make the text reference to table 28 not bold.
Make the caption for table 28 use the paragraph style "Table title", but without character styles (it's currently styled bold).
fixed in rev 13 editor's draft
Verified in rev 26 draft. The references to and captions for the tables (now tables 5, 6, 41) look fine in the HTML version.
