block-progression-dimension / fixed height table and variabl

[Briotti]

I'm not sure this is the right place for this question (it seems more related to FO, but not sure).

Anyway:

This block-progression-dimension is driving me crazy. Probably I didn't understood how it works... well, this is the problem:

I must create a table with 3 rows and 2 columns. The width of 2 columns is fixed (say 2cm and 16cm) and the height of the whole table is fixed too (say 20cm).

The 3 rows must have an optimum height of 30%, 40% and 30% (say 6cm, 8cm and 6cm). This is in the most cases.

Sometimes, depending on the content, one row can exceeds the optimum height: because of the condition of table height, can be useful if such growt can be achieved by reduction in height of another row.

Say for instance:

right case: row heigths are 6cm, 8cm, 6cm.

worst case (the last row needs 7cm because of his content): 6cm, 7cm, 7cm, or (better) 6.5cm, 7.5cm, 7cm.

I assumed (and probably I was wrong) that block-progression-dimension.minimum, block-progression-dimension.optimum, block-progression-dimension.maximum are designed for such purpouse.

No way to have this to work on a table:

What I'm missing?

Thanks for all suggestions

[Briotti]

I have found what I'm missing and put it the answer for other people that could have similar question.

Simply, the FO spec don't address a "block vertical justification". That's all.

To obtain such results, a double pass technique is required in order to check the resulting height by fop area three and correct as required.

Another way is try to guess the result height of the content, if it is simple. A possible approach is create an extension to paint the content on in memory image and retrieve some approximate height.
