Latex subtables side by side

I have been trying to setup those subtables as 2x5, but it is generated as one subtable per row. I have tried minipage, parbox, resizebox and nothing I know could pack 5 subtables into a single row. The code is shortened to 2x2 example. I would appreciate any sugestions. Thanks :)

If each table is going to be exactly the same, you can just use a simple pattern:

\hfill table \hfill table \hfill etc.

If they are going to be different, you can use tabular instead. Remember, if you want to place elements horizontally, you can't add extra empty lines. It causes LaTeX to start new paragraphs.

I created a grid of 3/2/3 tables. \subfloat[]{} is also a convenient macro to make sub-captions; it is defined in subfig. Any sub- related macro is only required if you want to make a reference to each individual table. If you don't, you can safely remove \subfloat along with subfig.
