Graphviz HTML tables were implemented prior to HTML standardization, but the subsequent RFC 1942¹ provides some guidance on “Recommended Layout Algorithms.” Following this, the W3C gave a slightly clearer articulation of essentially the same guidance when specifying CSS.² Many features discussed in this algorithm are not present in Graphviz’ variant of HTML (e.g. widths as percentages) or are not relevant (e.g. the derivation of maximum column widths seems only relevant if you are laying out a table within another elastically sized container like a browser window), but the algorithm is useful nonetheless. This function implements an adapted version of the CSS specification algorithm. Comments that include quotes are quoting the CSS specification.
