A question on Grid and nested lists

Hello,

thanks for your help on the variable dumping function in my earlier
post. I make good progress in learning Mathematica and I really like
it. However, here is again a problem where I am stuck.

In my dialog, I would like to lay out a table of parameters in two
columns. Each parameter consists of two or three elements, like

  param = {{text1, Slider[...], varValue1}, {text2, Slider[...],
varValue2}, {text3, PopupMenu[..]}, ...}

Since they are quite a lot parameters, I would like to put two
parameters in one row. I tried

  Grid[Partition[param,2]],

which work essentially fine, but there are these curly braces
indicating a list around each parameter. I think I cannot flatten out
on the second nesting level, because then I would loose the centering
of the parameters. So what can I do here? I tried

  param = Partition[param,2];
  param = Map[Grid[#]&, param, {2}]; (* Map[Pane[#... does not help
either *)
  Grid[param]

but that didn't help.

If you could help me here, that would be very nice.

Kind regards,
Karsten.
