I apologize for not knowing the correct term for this, but I want to put some kind of a infobox at the beginning of each section. What I want to ask about is for example on Wikipedia: you have this box on the right side where you can find information like population figures: http://en.wikipedia.org/wiki/Berlin. What's in this box might even be redundant to what is written in the text, but it makes it much nicer to (skim) read the document.
Ideally, I want this infobox to contain a tabular and I'd like it to be placed in the margin, but reaching inside the paragraph with the text floating around the box. Basically like this:
Can you tell me what the term for this is and what package I can use for this?
