If you think the plugin is an extra resource on your WordPress page load then you can go for online table generators that provide HTML code which you can place it in your WordPress post editor.
One such online responsive table generator is Ianrmedia.unl.edu, from there you can create any number of responsive tables and generate the code and paste it in the post editor.
Another such table generator is Quackit HTML Table Generator, unlike previous one this one allows you to select colors for your table. You can create a good looking table with different colors.
There are a number of online table generators which you can use. Hope you got what you are looking for. If there are any better ways to generate responsive tables then let me know in the comments below.
