I could've sworn SQL Complete used to show the column names for the inserted/deleted tables in the list members 

CREATE TRIGGER [dbo].[tu_Contact_StandingId]
ON [dbo].[Contact]
AFTER UPDATE
AS
BEGIN
    IF UPDATE(StandingId)
    BEGIN
        INSERT CapitaTransaction (CapitaTransactionId, CapitaPackageId, ContactId, CapitaTransactionTypeId, OldStandingId, OldStandingDate,
        NewStandingId, NewStandingDate, IsReport, SectionCodeId, CreatedBy, CreatedById, CreatedOn, ModifiedBy, ModifiedById, ModifiedOn)
        SELECT NEWID(), NULL, d.
        FROM DELETED d
        JOIN INSERTED i ON d.ContactId = i.ContactId
        WHERE ISNULL(d.StandingId, -1) <> ISNULL(i.StandingId, -1);
    END
END;

GO

ALTER TABLE [dbo].[Contact] ENABLE TRIGGER [tu_Contact_StandingId]
GO
