Space out controls in a panel

I'm creating txtboxes, labels, and cboboxes based on a users selection. These controls are being added to a panel.

I know I've seen this question here somewhere, but I can't find it. I would like to know how to space out these controls within the panel.

Any ideas?

A few methods:

1) Create a table with 100% width and insert each control in to their own table cell (the recommended method)

2) Use   to hard code multiple spaces. Not recommended due to copy paste issues. Looks like [control]               [control]

3) IE only. Create an img tag with a height of 0px and a width of how much space you want to seperate them.

4) Varying results: Create a DIV SPAN or LAYER between each with a style of style="width:xxxpx"
