Hi,
My 15yrs+ experience in JavaScript and application development are at your disposal.
From what I understood, you are looking for a web application to fetch the tables from a database, select a target table with targeted columns, query this table and display the results on webpage in a table format.
I also presume you will be using either MS-SQL or MySQL database.
This cannot be done in a normal client side website but through a node.js (javascript environment) server application which I can develop and provide to you as an API which will be called in your web app page.
The node.js server API will fetch the data and the webpage will be doing the table display part. My work will include both.
One granted the project, I'll be providing you an example of how this works which we can optimize together to produce the result you seek.
Thanks and looking forward to hearing from you and being granted the chance to serve you the best.
Kind Regards,
Badih
