@jonua Wow, if you are building a pro version, don’t forget to create an option to copy and paste a table, or import and export a table. Features like a table template to choose when you are creating a new table is good, but copy and paste a table from another post is a nice feature too. Maybe you can use buttons to offer this option, one button to copy to clipboard and other to paste from the clipboard, this content could be just a json, and send it to clipboard is just to make it easier to users, instead of copy some json code and paste there, you can hide this step from users. Think about that!
And I see no reason to use a tooltip interface to enter the text inside the cell, why not just put an input in that cell like any other table CRUD or HTML 5 content editable feature.
Another features always asked to me is to let users customize the content of each cell, using bold, italic, text on left, center, right. But these are much more complex to offer and users can build some shit with that. I prefer to use a CSS class to do that and the plugin just grab the data.
Hope you can build that pro version ??
