floats spanning columns?

floats spanning columns?

[-- Attachment #1.1: Type: text/plain, Size: 488 bytes --]

Hi there,

a simple one: Is it possible to span a \placetable float over multiple
columns defined with \startcolumns ...\ stopcolumns? Or do I have to
switch to column sets for that?

Yours,
Karsten

if a float is too wide it will be moved around; wide floats spanning columns and text flowing around it is not one of the strong points of normal columns

At least I didn't overlook something simple :)

Is there any easy fix to prevent the "table" from disapperaring when I
uncomment the \input knuth?

% -*- mode: context; coding: latin-9-unix; -*-

\setuplayout [grid=yes]

\definecolumnset[example]
\setupfloat[table][width=\makeupwidth]

\starttext
\startcolumnset[example]

\input knuth
%\input knuth

\placetable{Tabelle}
  \framed[width=\makeupwidth,height=4cm]{Hallo}

\input knuth

\input knuth

\stopcolumnset
\stoptext

well, you can't blame knuth for that one ... the problem is that the 
graphix is oved to a next page already but that page has no content
