TreeGrid in Vue and NodeJS server
Simple example without any installation; Creates TreeGrid dynamically by TreeGrid() function
Creates grid from and saves changes back to database on NodeJS server and SQLite3 database or static file
Source files:

StaticDef.js

 (static JSON layout),

Layouts/StaticData.js

The Static file example loads data directly without server and cannot upload changes. The SQL examples use
