Reuse existing table cell rendering logic, so render_cell() hook works

[simonw]

This plugin currently implements its own custom version of a table display:

datasette-search-all/datasette_search_all/templates/search_all.html

Lines 128 to 129 in 5b5f192

	var ths = safe(columns.map(c => autoescape`<th>${c}</th>`).join(""));
	var tr_rows = safe(rows.map(row => autoescape`<tr>${safe(columns.map(column => autoescape`<td>${displayCell(row[column])}</td>`).join(""))}</tr>`).join(""));

This means things like the render_cell() plugin hook are not respected.

Fixing this may require support from Datasette itself - maybe in the form of an API mechanism for fetching back just the table itself.

Relevant:

• Add ?_extra= mechanism for requesting extra properties in JSON datasette#262
• Redesign default .json format datasette#782
