    Note

    When it points back at a whole statement, the pronoun can move to the front for weight: 'That I couldn't do' stresses the refusal more than 'I couldn't do that'. An older idiom adds it to intensify what was just said, as in 'I got fed up, and that to a great degree'. There, 'and that' works like 'and indeed'.
