multipage table in columns

multipage table in columns

[Eckhart Guthöhrlein]

Hi all,

I have to build a table which should split over several columns
(probably two) and, if necessary, across pages.
I have tried this with

\starttext
	\startcolumns[n=3]
	\setupTABLE[split=yes]
	\bTABLE
	\bTABLEhead
		\bTR \bTD Head \eTD \bTD Head~2 \eTD \eTR
	\eTABLEhead
	\bTABLEbody
	\bTR \bTD once \eTD \bTD once~2 \eTD \eTR
	\dorecurse{120}{%
		\bTR \bTD test \eTD \bTD test~2 \eTD \eTR
	}
	\eTABLEbody
	\bTABLEfoot
		\bTR \bTD low \eTD \bTD low~2 \eTD \eTR
	\eTABLEfoot
	\eTABLE
\stopcolumns
\stoptext

This does something at least similar to what I had in mind :-)
Problems:

- As soon a page break is involved, the balancing algorithm gets totally
	confused. For example, the code above gives me three pages, with a
	single cell on the second one. The head is repeated only on the third
	page.

- How can I make a column break trigger head repetition instead of a
	page break?

- How to get the footer repeated at the end of each column, too?

Furthermore, there are some old messages concerning captions for
multipage tables, but I could not find a satisfactory answer. How can I
get a caption on the first page and something like "Table x cont." on
the following ones?

Thanks,
