I have a Lightning Web Component on my contact detail page. It displays the address. I have used \n while displaying different fields of address. When I deployed the code to another sandbox, the \n did not work. I verified the code and found it to be the same. I tried using '\r\n', '<br>' and '&nbsp' but nothing worked. How is it working in one sandbox and not working in other sandbox? Please guide. Thank You!

Please find the code and screenshots below.

Code for adding address in data

NOTE: The data is flattened because data is returned using a wrapper class.

//get data from apex class and flatten it
    @wire(getAddress, { id: '$recordId' }) wired(result) {
        //set the wired property for refreshing datatable
        this.refreshTable = result;
        if (result.data) {
            //create an array
            let preparedAddresses = [];
            //for each row of data, put a row in var named address
            result.data.forEach(address => {
            //create a row and add data in it
            let preparedAddress = {};

            //Address construction
            preparedAddress.Address_custom = (address.AddressID.Building_Name__c ? address.AddressID.Building_Name__c : '') +''+ (address.AddressID.Street_Address__c ? '\n'+address.AddressID.Street_Address__c : '') +''+ (address.AddressID.Street_Address_1__c ? '\n'+address.AddressID.Street_Address_1__c : '') +''+ (address.AddressID.PO_Box_Number__c ? '\nPO Box: '+address.AddressID.PO_Box_Number__c : '') +''+ (address.AddressID.City__c ? '\n'+address.AddressID.City__c : '') +''+ (address.AddressID.AP_State_Code__r ? '\n'+address.AddressID.AP_State_Code__r.Name : '') +' '+ (address.AddressID.Postal_Code__c ? ''+address.AddressID.Postal_Code__c : '') +''+ (address.AddressID.AP_Country_Code__r ? '\n'+address.AddressID.AP_Country_Code__r.Name : '');

            //push the row in array
            //assign the array to @track variable
            this.addresses = preparedAddresses;


<!-- datatable -->
        <div class="eighty-percent slds-table_bordered slds-table_striped slds-scrollable slds-m-around_medium">
            <lightning-datatable key-field="CRId" data={addresses} columns={columns} onrowaction={handleRowActions}

    Are you testing it on the same kind of browser? Both the sandbox have same API version? How are you opening the component? Jun 8, 2020 at 12:14

    Perhaps one sandbox is on Spring 20 whilst the other is on Summer 20? There could be differences in this upcoming release that are causing the difference in behavior. Which sandbox is which version?

    @sanketkumar @sfdcfox Thankyou for the response. I verified the versions of both the sandboxes. The sandbox where \n works has API version 48 and the sandbox where \n does not work has API version 49. What should be done in this case? How do I apply \n to the sandbox with version 49? Please guide. Thanks again!

    @sfdcfox '\n' is not working in summer 20 but it is working in spring 20. I read the release notes of summer 20 but did not find anything related to newline character.

  • @sfdcfox Thanks a lot! Wrap text shows the address properly. Is there a way to default the column action to wrap text instead of clip text?
