I'd like to know how to create dynamic table and save it in databse.

I looked into some Forge components about adding dynamic column but 

I am now trying this Forge (Dynamic Reactive Column) to see if I can do what I want.

Here is what I want .

For example,  you set number of rows and columns then generate dynamic table. (＊you can do it with this Forge)

Moreover, you set the table name (Ex: table1) and press "Save" to save the data for this dynamic generated table in database (Entity) . Here, you also save table name as the key.

After that, You click "to table list" and go to the table list to see the data of table you generated dynamically.

You select your table name here in dropdown and you can see the table you saved by table name. This means the table displays in the red circle area.

About data structure of Entity for dynamic table data you saved, I'm considering this kind of format like below.

This way, I'm guessing I could do what I want but I'm in trouble.

I'm stuck on saving the table data....

I wonder if it is impossible to implemment "add rows and columns and save in database"....

Do you have any ideas? or could you possibly give me any good advice?

I want to know how to do this.

Regards,
