Logging User Activity in MSSQL

[erickwidya]

currently i'm using TRIGGER for INSERT, DELETE, UPDATE which Insert new record to tblLogs
the table structure = UserName | DateTime | ActionTaken (I, D, U) | TableName

everything works fine until i realize that i missed important thing which is the "ColumnName" that user changed coz in here User seem easily forgotten what they have done, that's why i planning using the tblLogs

so the question would be How (if not involved complicated method)? or any other better method?

i open for any idea

thanks
