access vba - table columns not in form

There is a table and a form on the top of that table. Now overtime, users add in more columns to the table. The form still shows the old columns but not the newly added column. Is there a vba to do this so that it takes in the form name and table name as arguments and returns a list of columns that are in the table but not in the form itself  for example –
Function ShowNotinForm (myTblName,myFormName)
{
}
