regex – Search for a Text Not Preceded by a Pattern with a Variable Number of Spaces

I want to match instances of like to match the Table.Field that are not preceed by the words and or where.
However, there can be a variable number of spaces between these forbidden words and Table.Field.

The following regex represents what I would like to achieve, but it is invalid when using a PCRE engine because of the + quantifier and the alternation (and|where) inside the negative lookbehind:

(?

Table.Field
something Table.Field
 bTable.Field
Table.Field

and Table.Field
where Table.Field
and       Table.Field
where  Table.Field

Thanks
