Cloning Table + Save → Undefined Array Key

[Jones-S]

Describe the bug

I have a table that looks like:

And if I clone the table (without changing anything (no keys, no values) and save the post, I get:

yii\base\ErrorException: Undefined array key 7 in /var/www/html/vendor/verbb/tablemaker/src/fields/TableMakerField.php:200

Steps to reproduce

(Hopefully this let's it reproduce)

1. Create a Neo field (in my case "Page Builder" and add a Tablemaker block)

2. Add table and some content
3. Clone table (or rather the pagebuilder block including the table)
4. Save post

Note: Ok I think I was able to narrow the problem down.
Even If I copy paste the block to another page I get similar errors.
I think it is because of the Dropdown field. If the table is copied the Dropdown options are missing and therefore it fails.
I think that is the actual bug.
