Performance questions: lazy initialization + striping

I like DataTables, and for small tables, it is the best I have come across so far. For large tables, especially in combination with older browsers like IE8, but even newer ones, it is slow.

Is there a switch or variable which allows me to do lazy initialization of DataTables?

I frequently use DataTables just for sorting tables, so no pagination, no searches, ... As users often have no need to sort columns, it would be nice if the initialization of DataTables would be postponed until the first time the user actually clicks on a column header and requests a sort. This would of course make this 'first' sort a lot slower, but that is something that users can comprehend as they know something is going on based on a request they made. The initialization DataTables does on startup by default just seems like a performance issue to them.

Is there a switch to indicate that the original table is already striped?

I can set the 'even' and 'odd' classes (or whatever stripe classes you want) while generating the table. There is no need for DataTables to go over all rows and call the jquery addClass and removeClass functions. According to my profiling, this costs a lot of time.
