sort does not work when using certain formatters

I am setting a column to be formatter:‘link’ and sorter:‘string’ and the column does not sort properly.

NOTE: I do have NULL and blank values in the cell, does that matter?

{ "title": "Url", "field": "url", "formatter": "link", "sorter": "string", "editor": "input" },

Likewise with date inputs

Here is the javascript for the date column { "title": "Start At", "field": "start_at", "formatter": "date", "sorter": "date", "sorterParms": { "format": "YYYY-MM-DD" }, "editor": "input" }

I am including moment.js

Hey @AmmarKureja

If you get that message it means that the global variable moment has not been setup when you included the moment library.

if you have used a require function to include moment then you need to use:

global.moment = require("moment");

I hope that helps,

Cheers

Oli 😃
