"""Pin the pure splitTableRow helper (static/js/markdown/tableRow.js).
|
|
|
|
Driven through `node --input-type=module` (same approach as test_compare_js.py);
|
|
skips when `node` is not installed.
|
|
|
|
Regression: the old split filtered out every empty cell, so an intentionally
|
|
empty interior cell ("| a | | c |") collapsed the row to 2 columns and
|
|
misaligned it with the header.
