How to have multiple exposed filters in a block that affects multiple views content panes in a panel?
Select one of your displays (lets say table1) and add (or recreate) the other displays as attachments.  Then only display table1 on your page and all other displays should tag along with it. Then expose the filter for table1.

Here's a good overview:

UPDATE:

If you just want disconnected views to pick up on one exposed filter then this might do the trick:

It gives you configurable blocks with filter options. These options are made available as contextual filters so your views don't need to have the exposed filters.
