field is moving when I hide a field that is place on the same row

Hi all,

I have a trouble, for some reasons I want to hide a field on a form

an example of my form:

field1 :   xxxxx               field2 : yyyyyyy  field3 : zzzzzzz

If I hide field 1, when I try to load my form, it will display as  below:

field2 : yyyyyyy  field3 : zzzzzzz

how to do this ?

                                     field2 : yyyyyyy  field3 : zzzzzzz

thanks
