Hide table columns that are empty for every row

[ibuilder]

Found by standing up a real WordPress site with the published v2.0.4 ZIP, serving it over HTTP, and reading what a visitor actually receives.

The problem

Email suppression is on by default, so [procore_team] rendered this:

headers: Name | Role | Company | Email
email cells: 4 total, 0 non-empty

An Email header above a blank cell for every member — visible dead weight on the most commonly used shortcode, on every default install.

The fix

Columns that render nothing for any row are dropped before the table is built. Now:

headers: Name | Role | Company

This also covers a column no record happens to populate, and the filter never reduces a table to no columns at all.

Tests

Two: the column disappears when email output is suppressed, and survives when both opt-ins are on. 103 tests, 390 assertions. PHPCS clean.

What else the test site showed

Everything else held up. Verified over real HTTP, not by asserting on strings:

Unconfigured install	Visitors get a neutral message; admins get actionable guidance naming the setting
Conditional stylesheet	Present on pages with output, 0 refs on a page without
Admin, served over HTTP	All six tabs render; secret never in the HTML; masked placeholder present
Status screen	Reports AES-256-GCM, rate limit, circuit state; no token in any code block
AJAX Test connection	Driven through admin-ajax.php with a real nonce — 6/6 stages, 16/16 endpoints readable
Nonce enforcement	Bogus nonce → -1; no cookie → 0
Map	3 points with coordinates, inactive project filtered, no third-party script
PHP notices in served HTML	0

I also chased two false alarms to ground rather than reporting them: a stylesheet that looked like it loaded on a plain page (wrong page was being served) and an apparent token leak on the Status screen (the admin bar showing the username demo, which collided with my mock token value).
