Export datatable excel with lot of data

[mthai]

Hi,

I would like to export a datatable with lot of datas (100 000) and i also use rich:columns.
When i was exported datatable without rich:columns, does work but if i use rich:columns, i have a out of memory

How can we fix this?

Thank you and sorry for my english.

Hmm, hard to tell. How much mem do you have. Perhaps try to profile it to see what in the rich:columns access is eating up the memory...
