Hi Aidan,

The observed error suggests using an older version of the Editor package where the kendo-editor-insert-table-button component is not yet available.

The support for tables was added in the 0.8.0 version of the Editor component:

Please make sure that you are using the latest versions of our packages that contain all current features and fixes. It is recommended to remove the package-lock.json file and the node_modules folder before running a clean npm install to ensure that the latest versions and their correct dependencies are actually installed.

Here is a quick guide for updating all Kendo UI for Angular packages in one go:

I created a Stackblitz demo with an older Editor version (0.7.0) where the described error is observed:

... and the same one with the latest version installed where the Editor is working as expected:

I hope this helps.
