[NTG-context] A side by side float that takes advantage of the margin

I have a situation when I have to put side by side two floats (a table and figure). My current code is \placetable[here][label]{caption}% {\\placesidebyside {table code}{figure code} } The problem is that sometimes the combined width of table and figure is bigger than the textwidth. I would like the combo to be centered across the page, not starting from the left margin of the text and invading the right margin only. How can I achieve this? -- Giuseppe "Oblomov" Bilotta
