Tobias, We have a similar need for auto table sizing, but we also have an additional need for "table wrapping", so we simply had to come up with an alternative solution. Since the FO is generated from XSLT, we can pass the page width and margin values as parameters to the XSLT stylesheets that can be used to get the "body width" of the table. Then, we have a complicated algorithm that analyzes the text that will go into each cell and calculates its approximate width based on the number of chars in the largest string in that column. We use that value in combo with the body width to know how many columns will fit on the page and how wide each column needs to be.
At this point in time the character metrics are stored in a lookup table for a controlled set of fonts and font sizes. Certain combinations of characters cause the metric approximation to get all haywire, though, so we're beginning to look at a way we can possibly use XSLT extension functions to have Java and its FontMetrics class better approximate the width and height of the strings. Overall, however, the algorithm doesn't change. >From what I've read on the mailing lists before, yes, there is a patch >somewhere in the Bugzilla queue that attempts to offer some auto table sizing >algorithm but that it doesn't yet work for all cases and is an *extremely >complicated* algorithm to complete.

Furthermore I'd like to know if there are already approaches or ongoing development on this issue. Do you know how other FO processors capable of this feature have solved the problem. Would be nice if you can provide me additional information what happend so far or not - so maybe we can help and work on/contribute a solution in one of the next releases.
