Client. Should. Die.

Large table which needs to be filled with data - data needs to be prepared because there can be gaps in the data (data represents orders of supplier per day).

So layout is like this:
supplier1 supplier2 ...
date orders
date orders
date ....

Which already is fun. Not. Fetching data with several filters, prepping
data and assuring ordered output without gaps was painful...

The number of suppliers can be anything between 1 or >300 - limited is only the date range. there is an click event on every mofo column for enlarging the whole column and loading additional data via ajax.

Now in all this cringy mess.... I had to make it scrollable.

Horizontal and vertical.

wasn't much fun either.

Can someone please kill any client with the task : make this gigantic shit pile of dynamic table behave like Excel?
