feat: format tables in most cases

[QuadnucYard]

Features:

• Relax the judgement for tables (grid, table), special rows (header, footer), and special cells (cell, hline, vline), without requiring prefixes (grid., table.). Treat spread args as special cells. This is expected to introduce more false positives, since we do not rely on a language service that checks function signatures at runtime. Maybe users can utilize this feature for custom tables.
• Format header and footer as tables. Their column number derives from the container.
• When there is any special cell, do not reflow cells even if the column number is determined. We preserve your grid structure.
• Format tables with line comments (but not block comments). A line comment always occupies an entire line instead of attaching.

Incapable cases are reduced to

• Containing any block comment
• No positional args. It can be bad under grid layout.

• closes Treat imported header same as table.header #196, although it's not a precise solution.

This prepares for table alignment.

For better visualization, it is better to put cells in a row on a single line, even if they are too long.
However, if any cell in a row is multiline, that is worse than putting each cell on an individual line.
In this case, break-suppressing will not help.

We may limit table alignment to cases where cells in the row are all single-line.
