table-row-column-alignment

v4 default severity was warning. v5 splits into four rules. Alias expands to all four until v6.

New rule	Check	Default severity
no-table-cell-overlap	Overlapping cells	error
no-table-span-overflow	rowspan past the row group	error
no-empty-table-track	Row or column with no anchored cell	error
consistent-table-row-length	Uneven column counts (spec allows growing the table)	warning

v5 models the grid with HTML LS §4.9.12.1 Forming a table. New reports include empty tracks and rowspan past a row group. A rowspan that exactly fills the rows below it is no longer reported as an extra column (v4 cell-counting false positive).

If overlap is reported, the other three rules skip that table (the grid would be speculative).

markuplint:a11y enables all four as named groups. Restore v4 warning-level table-model checks by setting those three rules to "severity": "warning".
