I have read through this example but I have one question…
When you provide the columns dynamically, how can you call methods because the function in quotes is not valid and without quotes is invalid JSON?
var json = ‘[{
“columns”: [
{“text”: “Name”, “datafield”: “name”, “width”: “250” },
{ “text”: “Beverage Type”, “datafield”: “type”, “width”: “250” },
{ “text”: “Calories”, “datafield”: “calories”, “width”: “180”, “cellsrenderer”: “cellsrenderer”},
… etc
