Add option to search only one column

[ufechner7]

It would be very useful for me if I could search for a value, for example 14 in a specific column only, because if I search for it globally I get far too many irrelevant hits.
In my application 14 in the column Flags indicates a CAN bus error frame, but it can also appear (often) in other columns without any special meaning.

Hi @ufechner7 !

TerminalParger is not data aware, meaning that I just cannot know where a column in a table begins or ends. We can, however, limit the search with respect to a certain column interval, but I refer to text columns, not table columns. Will it work?

Bump!
