@Rajat-Dabade this method does not take unit into account please fix this one

example:

ideally this downloading of csv should be handled from the backend itself taking the account of pagination in future it will be hard for the user/ client to aggregate the data

yeah..when pagination comes to play or there is huge data the search should also query the backend. But this data is not supposed to grow big so we should be good

1. Name should be the 1st column
2. P50 should be P50 (in ms) and the same for the other P95 and P99
3. P50 (in ms) value should be in ms. The current values are in nano.
4. Change styling after UX consultation in a separate PR @GeekBoySupreme

[ankitnayan]

• It's Error (%) and not Error Count and the value is also incorrect
• the values of P50, P95 and P99 are duplicated and incorrect. Please verify data sanity before pushing any changes
• append name of the service to filename? top-operations-customer.xls/csv

@Rajat-Dabade can you also check why the numbers are treated as text in xls but as numbers in csv. We should treat them as numbers. Selecting multiple values in the column P50 should show Sum for numbers.
