Fix data dashboard - data_loader.py

[yongzheJIN]

fix always use the first column as row Name+handle value None and no data
We cannot use try Catch to ignore the ERROR.

Description

To organize the data for data dashboard. To just regard the first column as name is pretty rude. I find a method that will meet no errors(while the sql get from GPT is right). It can handle if there are no data in mysql database or there are all None data in mysql database.

How Has This Been Tested?

Even the data in the mysql database is None is still ok.
