Add hyperlink dynamically to the Name column in lightning-datatable in LWC


I am trying to display a lightning-datatable with few columns in lightning web component. As I get the data from apex, I try to add new column in the JS controller dynamically with hyperlink (as we did in aura component), but it does not allow me to add this new column.

Aura Component
component.set('v.mycolumns', [
            {label: 'Account Name', fieldName: 'linkName', type: 'url', 
            typeAttributes: {label: { fieldName: 'Name' }, target: '_blank'}},
            {label: 'Industry', fieldName: 'Industry', type: 'text'},
            {label: 'Type', fieldName: 'Type', type: 'Text'}
action.setCallback(this, function(response){
            var state = response.getState();
            if (state === "SUCCESS") {
                var records =response.getReturnValue();
                    record.linkName = '/'+record.Id;
                component.set("v.acctList", records);

I am trying to do similar implementation in LWC but no luck. Can someone please help me on this.

Thank you Anas,

Actually, I was trying to add 'linkname' in the response which was returned by apex method, and this was called by using Wire
adapter, where result is stored in cache which becomes read only (as apex method is defined as @AuraEnabled(cacheable=true)).

So, I tried to call the same method Imperatively (Apex method is written without @cacheable annotation) and I was later able to add additional link 'linkname' in the result.
