no admin user can't see add button even the ''create paragraph content" permission is granted.

this patch is trying to fixed it.

I don't quite understand can you explain?

https://git.drupalcode.org/project/paragraphs_table/-/blob/8.x-1.x/src/P...
$this->customPermissions['create'] always return FALSE, which cause the code for $addButton check always failed.

There is also confusing on edit/delete/view link permission check.
If the user doesn't has "administrator" roles, they always can't see edit/delete/dupulicate links, even the permission "bypass paragraphs type content access"/"delete paragraph content XXX" permission is granted.

https://git.drupalcode.org/project/paragraphs_table/-/blob/8.x-1.x/src/P...

because it supports field permission not paragraphs permission

Thanks, after enable field_pemissions, works as expected.
I think it's better to document it.

it's written in presentation of module
