A cell of a table (Lexical type "tablecell").
header_state ("headerState") is a set of bits: 0 for a data cell,
1 for a cell of the header row, 2 for a cell of the header column,
and 3 for both. A header cell renders as th, with scope="col" in
the header row and scope="row" in the header column; a data cell
renders as td. col_span and row_span ("colSpan" and "rowSpan")
are at least 1, and at most 1000. The editor's backgroundColor,
width and verticalAlign keys stay in extra, and the renderers do
not use them.
A cell is valid only in a Kotoba.Nodes.TableRow. It holds blocks
(paragraphs, headings, quotes, lists, code blocks, horizontal rules and
attachments) and inline nodes, but no table.
In plain text, the cells of a row are separated by a tab, and a cell
keeps its text as it is (a cell with two blocks has two lines). In
Markdown, a cell is one line: its line breaks become <br>, a tab
becomes a space, and | is escaped.
