Well, I thought location would center the table. Before and after (with
\startalign) crash compilation. Aligning the whole table doesn’t seem to
make any difference. Sorry, but how can I center the table and not its
contents?

Use

\startlinealignment[middle]
or
\startplacetable[location={force,none}]


Many thanks for your reply, Wolfgang.

Only the second option works with the real table. The first one crashes
compilation.


The second issue is about rulethickness: would it be possible to specify
different dimensions for each frame (top, bottom, left, right)?

Disable the normal frame and use a metapost background with
different values for all borders.


MetaPost is unknown to me. How would it be with this minimal sample?
There is a second method which let you create your own argument for the leftframe,
rightframe etc. keys.

\installleftframerenderer {small}{\blackrule[height=\overlayheight,width=1\linewidth]}
\installleftframerenderer{medium}{\blackrule[height=\overlayheight,width=2\linewidth]}
\installleftframerenderer   {big}{\blackrule[height=\overlayheight,width=3\linewidth]}

\starttext

\framed{Text}

\framed[leftframe=small]{Text}

\framed[leftframe=medium]{Text}

\framed[leftframe=big]{Text}

\stoptext
