time passed between 2 dates by Customer ID

Hello,

i want to calculate in script, by every Order ID of the following 3 customers the time difference (in days) from their previous order.

In case of their first order, the Diff should be 0.

for ex, for Customer ID 1, his second order (22.02) will have on the desired calculated column 5, because his first order was 5 days ago (17.02).

P.S. i don't have the table sorted like in this example.

132/22/20205
1105/18/202086
253/30/20200
264/20/202021
311/2/20200
