Willi Egger wrote a [[My Way]] how he set a typesetter's lead type case: [http://dl.contextgarden.net/myway/NaturalTables.pdf Use of natural tables]
To place a table use:
<texcode>
\placetable{Caption}
{\bTABLE
\bTR \bTD One \eTD \bTD two \eTD \eTR
\bTR \bTD One \eTD \bTD two \eTD \eTR
\eTABLE}
</texcode>
Be aware of the brackets surrounding the bTABLE ... eTABLE part!
<texcode>
