I think I managed to solve this.
In the TinyMCE folder of WordPress, the table plugin is not included. Using the same code as above, I did the following:
1- I downloaded the table module from this link: https://www.tiny.cloud/get-tiny/custom-builds/ I unzipped it and uploaded the "table" folder to /wp-includes/js/tinymce/plugins (In this folder, all the plugins called in the first array are located). Therefore, naturally, TinyMCE in WordPress does not have the table plugin. But now, by manually uploading it, it does.
2- In the code above, I just added the plugin call in the first array ('table') and then called it after the "|" ('table').
Just save your code and boom... it's working!

The code is great. Any ideas how to enable the Table option?

Hi, Thanks for your suggestion.

Step : I used the code through a code snippet. Step 2: Uploaded the table folder in the wp-includes/js/tinymce/plugins directory. Step 3: Added 'table' in plugins array & '|', 'table' in the toolbar_buttons array.

Getting this error " Failed to initialize plugin: table"

I checked the "Sources" from Inspect. The table/plugin.min.js file is loaded.

Any suggestions to resolve it?

###UPDATE:
Finally worked for me after some some times later. Maybe I was facing cached issue. Worked both for regular page & JetPopup.
