Implements cell spanning syntax for tables based on discussion in jgm/djot#368 Syntax: - `^` in a cell means it's spanned from the cell above (rowspan) - `>` in a cell means it's spanned from the cell to the left (colspan) Example: | Category | Item | Price | |----------|--------|-------| | Fruits | Apple | $1 | | ^ | Banana | $0.50 | | ^ | Orange | $0.75 | This renders "Fruits" with rowspan=3. Example with colspan: | Header | > | |----------|--------| | A | B | This renders "Header" with colspan=2. Features: - Rowspan via ^ marker - Colspan via > marker - Works with cell and row attributes - Preserves alignment - Handles complex combinations of rowspan and colspan

The < marker now points toward the source cell (to the left), consistent with ^ pointing up toward its source cell. Also added additional test cases: - Combined colspan and rowspan on same cell - Multiple colspan groups in same row - Rowspan across multiple columns - Literal < in cell content (not treated as marker)

Summary
Implements table rowspan and colspan support using
^and<markers as proposed in jgm/djot#368Syntax
^in a cell means it's spanned from the cell above (rowspan)<in a cell means it's spanned from the cell to the left (colspan)Both markers point toward their source cell, making the syntax consistent:
<points left ← toward the spanning cell^points up ↑ toward the spanning cellRowspan Example
Renders "Fruits" with
rowspan="3".Colspan Example
Renders "Header" with
colspan="2".Combined Example
Renders:
colspan="2"rowspan="2"Features
^marker (cell spanned from above)<marker (cell spanned from left){.class})<in content (e.g.,a < b) not treated as markerRelated
