Hi,

I want to typeset a table where some of the column headings are really long, 
while in the columns itself consists only of numbers.
Therefore, my idea was to rotate the column headings but not 90 degrees (I 
found some solutions for that) but 45 degree.

It then would be beneficial to push together the rotated cells, so the text of 
one cell actually starts above the previous cell.
Do you know, how to achieve that?

Here is a minimal example:
```
\startsetups[table:rotated]
        \setupTABLE[frame=off]
        \setupTABLE[row][first][bottomframe=on, style=bf, align={center, low}]
        \setupTABLE[row][2][align=flushright]
\stopsetups

\starttext
\define\tablerotate{\dontleavehmode\rotate[rotation=-45, location=high]}
\bTABLE[setups=table:rotated]
        \bTR \bTD \eTD \bTD \tablerotate{Water buffalo} \eTD \bTD 
\tablerotate{Mexican redknee tarantula} \eTD \bTD \tablerotate{European turtle 
dove} \eTD \eTR
        \bTR \bTD Amount of legs \eTD \bTD \digits{4} \eTD \bTD \digits{8} \eTD 
\bTD \digits{2} \eTD \eTR
\eTABLE
\stoptext
```
I would like to achieve that the text "Mexican redknee tarantula" is typeset right and 
above of "Water buffalo" so that the single columns have a width that is similar to the 
width of the single digit coming in the second row.

To visualize this, I patched the PDF of the above example to the desired 
result. See the attachment.

You can use Metapost.

\startuseMPgraphic{tableheader}{text,rotation}

  label.lft("\strut\bf\MPvar{text}",origin)
    rotated \MPvar{rotation}
    shifted (\the\strutht,0);

  setbounds currentpicture to unitsquare

xyscaled(\the\struttotal,sin(\MPvar{rotation})*\the\widthofstring{\MPvar{text}});

\stopuseMPgraphic

\starttext

\bTABLE[frame=off]
  \bTR[align={middle,low}]
    \bTH \eTH
\bTH[width=3em] \dontleavehmode\useMPgraphic{tableheader}{text=Water buffalo,rotation=315} \eTH \bTH[width=3em] \dontleavehmode\useMPgraphic{tableheader}{text=Mexican redknee tarantula,rotation=315} \eTH \bTH[width=3em] \dontleavehmode\useMPgraphic{tableheader}{text=European turtle dove,rotation=315} \eTH
  \eTR
  \bTR[topframe=on,align=middle]
    \bTD Amount of legs \eTD
    \bTD 4 \eTD
    \bTD 8 \eTD
    \bTD 2 \eTD
  \eTR
\eTABLE

\stoptext
