To get that style of numbering, you will need to either use a SEQ field with a number formatting switch, such as
{ SEQ Num # 00 }
or, define a New Multi-Level list following the method detailed in the article "How to create numbered headings or outline numbering in your Microsoft Word document" on the following page of the Late Shauna Kelly's website:

Selecting 01, 02, 03 as the number format to be used
Indeed, that's what I ended up using.
The drawback of this is subsequent numbering in a table column would not be generated automatically as you add a new row. Unlike the more common (single digit) numbering.
I had to copy each number to the next (new) row in the table and press F9 to update the field. Well, it does the job as far as the end result is concerned, but feels like a work-around more than a solution :)
Thank you for your care.
Kind regards
