As you know, an HTML <table> element can have a lot of geometry variation for width and height of cells and the whole table overall. The browser does a lot of work re-sizing cell height and width to fit "nicely." in the available window size. A huge range of variation exists in table geometry, of course.

When an <object> contains an HTML <table>, that former tag can specify width="100%" (or some fixed pixel width), which render pretty well for nominal cases. However if the table height as-rendered is rather large, setting height="100%" doesn't yield a very tall table, and it's not dynamic as the browser window changes. And using fixed pixel height= is unhelpful if you don't know the as-rendered height in advance. If you're relying on the browser to arrange the cells in its default behavior.

Does anyone know any tricks to get <object> to better respect the dimensions of an HTML <table> inside it? I can picture the <object> inquiring its contents for height or width attributes on a root element, e.g. SVG markup has these and resizes the containing <object> smartly. Would it help to fake out <object> by including these attributes in the <table> markup? (I've tried, but no joy in limited attempts).

I wish <object> were smarter about this, but apparently it's not.
