OK, and my question was solved.
Your answer and advice was correct. When I checked the table-embedded page not the preview, there was the both input icon and Font-Awesome icon.
Now it is good.
However I am not sure why there was not the icons on the preview….
Anyway, it worked and thank you for your help!

Thank you for your prompt answers.

I have one more question about the inserting Font-Awesome icons in the cell.
Can you explain what is the most simple or easiest way how, in your answer, the appropriate font file is loaded ?? Can you introduce the steps in detail? Because I am a beginner for the both Tablepress and Font-Awesome.

When I searched on the topic there are two ways for Font-Awesome,
to use CDN and to use saved Font-Awesome icon files.
To use CDN way, where should I add and input the Meta link lines for the Tablepress?
Or, to use saved Font-Awesome icon files. where should I save the icon files for the Tablepress?
Can you show me examples ?

I need your helps more. Thank you again.
