formatting problem when import a excel form to Adobe form.

Have you tried using LiveCycle Designer to do the conversion? It might give you better results, and it's an editing program, which Acrobat is not.

But, as you've already found out, converting from Excel is not a good choice. You'd be much better off starting with Word. I image you started with Excel because you needed calculations? When Acrobat converts to PDF it converts the look of the form, not the interactive fields, which is why Word is better. Then you have to add the fields with form fields recognition and manually.

Take a look at these "First Form" tutorials:
