what's the deal with the span tag and tables tags?

by: developer | last post by:

Does anyone know what is the way IE treats span tags(<span>) and table tags(<tr>, <td>)? Should the <span> tag be encolsed in tds and trs if it placed with other elements that are in a table? Can the span tag itself contain table tags within it? I have some scripting code and when I wrap the span in table elements it does not find the html within the span.
