Clipboard HTML is read only as far as the pasted text's shape (clamped
to the sheet) and at most 1,000,000 cells; colspan/rowspan are clamped
to the sheet extent before expanding, and rowspan now keeps later rows
in their columns.

Spreadsheets put an HTML table next to the tab-separated text; Excel
(x:num) and LibreOffice Calc (sdval) record each cell's number there.
Paste now reads the HTML flavour (new paste_html host service, arboard on
desktop) and edit.paste takes an optional html param: a field that would
paste as text becomes the recorded number when the HTML cell shows the
same text, with an inferred format ("Rp"#,##0.00) that renders it back
identically.
