a) In a table headings, do I need to ensure it is grammatical? e.g. Period Start date and Period end date.
Does it mean it is always in this structure for headings that have 3 words, that is Noun+ Verb+ Noun or Verb + Noun.
b) Another example of the name of a heading e.g. Patient name; patient is a noun and name is a noun. Does it mean if there are two words then we use noun followed by noun.
Other examples include: Commencement date [ noun+noun], shoes size [noun+noun], etc.
