I would let your EA write everything to a local file and have a local
Powershellscript that composes the actual web-page (your table) and post that onto
the (remote?) websever...
Look (google) for existing code in the net.
Beside that you can write the whole page in your EA and post it with WebRequest - there seems to be scripts: https://www.mql5.com/en/code/12296.
But I don't know whether this works in mt4 - I have read about problems using 'post'.
You can also do in your EA to send signals in a format such as JSON through WebRequest() POST. For example the following type:
"openedAt":"2016-09-02 12:30:00","closedAt":"2016-09-02 13:15:00","bid":0.75911,"ask":0.75921,"timestamp":"2016-09-02 12:38:53"
I second the suggestion by Mikhail Dovbakh
to output the data to your site via WebRequest(). You just have to ask your Web Developer to setup a Web Service/API on the web side with some security to prevent hacking.
However, also remember that MetaTrader has a FTP Publish function for automatically publishing reports on the account state and its history as well. The reports can also be tailored to your requirements by setting up a template for it.
