Change 395477 had a related patch set uploaded (by Eflyjason; owner: Eflyjason):
[mediawiki/core@master] parser - Ignore whitespaces between wiki table syntax and table content
By the way, currently Wikipedia already has the expected output because of Tidy (https://www.w3.org/People/Raggett/tidy/). But I think this patch is still needed for general Mediawiki sites.
Yes, for ensuring consistency (there can be different parsers, across Special:ExpandTemplates, preview mode, etc.)
And it's bad to rely on the subsequent parsing layer to fix the output...
Change 395477 abandoned by Eflyjason:
Parser: Ignore whitespaces between wiki table syntax and table content
Reason:
"This has been fixed generally as part of https://phabricator.wikimedia.org/T157418"
The current result of the test case is
<table> <caption>? </caption> <tbody><tr> <th>?</th> <th>?</th> <th>?</th> <th>? </th> <th>? </th></tr> <tr> <td>?</td> <td>?</td> <td>? </td> <td>? </td></tr></tbody></table>
The  s are now away.
