A basic tool belt at top of each reports

[EFFICIENTCORPORATES]

Is your feature request related to a problem? Please describe.

This issue has been partly covered by #79 but would want to just make it complete in terms of utility and pervasiveness.
Currently, the reports that are being displayed are a simple table that reads through all rows of the model.
As of now there are only basic reports like Vendor , Customer Master, but in future, there will be multiple reports like Sales register (Invoice Wise Sales with Customer Number) , Purchase Register (Vendor Wise Bills and amounts)

As of now, These reports lack basic table operations buttons. There is no basic Sorting, Filtering, Subtotal, Summing Up.

Describe the solution you'd like

A tool belt with icons which can perform the most Basic SQL operations like the Sum of a Totalizer Column, Grouping of Columns, Sort By, Filtering any Columns, Find in Table, Show / Hide Columns . Multi Level Sorting..!

This tool belt should be visible for all reports that are displayed ...
The user Interface can be discussed upon..

Also , a Download to Button with option to download as Excel, Feather , Pickle, Csv, Txt, Pdf , even Copy to Clipboard option file needs to be built on..!

A cherry on cake would be , if using the Google API, the report can be opened in a Google Spreadsheet (in a click) to a new tab
