In-Line editing not working with Salesforce LWC implementation

[SiddharthNagpal]

I am trying to follow the Salesforce documentation to enable in-line editing by adding the editors to the column definition and using a 'Slicker' prefix as shown below,

// Create columns this.columns = [ { id: 'activityName', name: 'Activity Name', field: 'activityName'}, { id: 'armAssignment', name: 'Arm Assignment', field: 'armAssignment'}, ...visits.map(visit => ({ id: visit, name: visit, field: visit, type: Slicker.FieldType.number, editor: { model: Slicker.Editors.integer } })) ];

I have also added the following grid options,

enableCellNavigation: true, editable: true,

I am able to render the table with Data but I get the following error when I try to include
type: Slicker.FieldType.number, editor: { model: Slicker.Editors.integer }
in my column definition.

error message --> _Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'number')

Is there some documentation that i am missing or is there another way to handle this in Salesforce.
I would appreciate if I can get a prompt response. TIA!
