Simple know-how: output your data as HTML (text!) file with <table>. All you need: text output (Fortran formatted or list i/o) plus minimal knowledge of HTML (see Source in your browser).
Then you can import these tables in your favorite text processor, or print them by browser directly.
You may paint tables with border & others attributes, if you wish.
That approach works fine with any language, no need for special report generators, you have a free hand, free will and freedom of speech...
And your Fortran can produce complet formatted docs on the fly...
