The problem is the column layout algorithm tries to give the column the maximum width of the column text as it would be UNwrapped. If the window is not wide enough, it proportions the available width to the columns, based on the maximum width of their text UNwrapped. Thus any wrapping that occurs is not factored into proportioning the column widths optimally. What should happen is that after laying out the table with the proportioned widths per the current layout algorithm, there should follow be a second-pass, where (per column) the minimum size of the wrapped words for each column (aka the excess wrap whitespace) are removed. I was incorrect in my first post to ponder if this had to be gradient search or multi-pass-- rather it is a deterministic 2nd pass. I think it can be explained simply in ascii, I will add *********** below where the excess space is: >> ? ( Recurse |*********** Recurse ? ?, First-set... >> ***********? ? Fi(n), n ? N, n = head(w) ) First-set... >> where Recurse is (Fi(n) \ ?) ? Fi(tail(w)) *********** First-set... >> >> The excess gap can be as large as the width of the "Recurse ? ?,". Notice that *********** is less than or equal to the width of "Recurse ? ?,".
