Hi, I've noticed a few issues with natural tables.
1. Embedding images into tables do not scale correctly using recent ConTeXt releases. They do using the TeXLive 2007 version (2007.01.12). It does not matter whether I use factor=max or fit. I find I need to use the \vbox{\noindent{...}} structure to make the picture obey table's align= setups. test1.tex and weight.eps/pdf demonstrate this behavior. I attached pdf's to show the "good" behavior.
