You can use these ways
A. Use a Table Generator Tool
#1. You can Google, a lot of online tools. When you finish creating a table, they usually provide you with an embed code. Something like this.
#2. Edit Page where you want to add a Table > Add a Code Block
#3. Paste embed code. You will have result.
Here I used this tool: https://divtable.com/generator/
B. Use Table Block
You need to install this plugin first. When you install it, you will see an option “Table” when you ADD BLOCK.
