Overview

Fast inline cell renderers — Ruby equivalents of the crud_components/fields/_*.html.erb partials, built with the tag/link helpers so a big table skips one partial render per cell (the dominant cost: a partial cell is ~200µs, this is ~10–20µs). Output matches the partials (same elements, classes, links, escaping).

Used only when the renderer is one of these built-ins AND the host hasn’t overridden its partial (Base#render_cell checks both). markdown/asciidoc and any custom ‘as:` renderer keep using their partials.
