FIX: Spreadsheet only loading for one instance

This commit moves spreadsheet logic to a component which resolves the issue where the spreadsheet only loads the first time the edit modal appears.

-## Edit Table Functionality (WIP)
-
-Known Issues:
-
-- After viewing an edit table modal once, a reload is required for it to work again or with another table, otherwise the following error appears:
-  
-```js
- You need to pass a node argument to Importabular, like this : new Importabular({node: document.body})
-```
-
-This is possibly due to not having a unique id? Perhaps moving functionality to a component will resolve this.
