two issues with xtables

two issues with xtables

[Pablo Rodriguez]

Dear list,

I have the following table:

    \starttext
    \startalign[center]
    \startxtable[location=middle, frame=off, bottomframe=on,
        topframe=on, rulethickness=2em,
        %~ before={\startalign[center]}, after={\stopalign}
    ]
    \startxrow
    \startxcell test \stopxcell
    \stopxrow
    \stopxtable
    \stopalign
    \stoptext

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?

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

Many thanks for your help,

Pablo

Use

\startlinealignment[middle]
    \startxtable
     ...
     \stopxtable
\stoplinealignment

or

\startplacetable[location={force,none}]
    \startxtable
     ...
     \stopxtable
\stopplacetable

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

Many thanks for your reply, Wolfgang.

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

MetaPost is unknown to me. How would it be with this minimal sample?

    \starttext
    \startxtable[bottomframe=on, topframe=on, rulethickness=2em]
    \startxrow
    \startxcell test \stopxcell
    \stopxrow
    \stopxtable
    \stoptext

Many thanks for your help,

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

Many thanks for your reply, Wolfgang.

I’m afraid that only leftframe seems to work with latest beta:

    \installleftframerenderer{big}{\blackrule[height=\overlayheight,
    width=3\linewidth]}

    \starttext

    \framed{Text}

    \framed[leftframe=big]{Text}

    \framed[bottomframe=big]{Text}

    \framed[rightframe=big]{Text}

    \framed[topframe=big]{Text}

    \stoptext

I have no idea about what I may be doing wrong.

Many thanks for your help,


Pablo

You need to add \installrightframerenderer, \installtopframerenderer, and 
\installbottomframerenderer.

Many thanks for your help, Aditya.

Of course, you’re right. I totally overlooked it. I misread
\installframerenderer.

I wonder whether a common \installframerenderer would make sense here.
It would simplify code writing. Or at least I think it may be useful.

Many thanks for your help (and sorry for still being asleep  :-)),

Excuse my nonsense. I have just realized that lines must be different
for top/bottom and left/right.

Sorry for the noise,
