Hyperlink a Record in lightning:datatable

We can take help of the type: url and typeAttributes: {label: { fieldName: 'linkLabel' }} to show some useful link label of the column;

Working with Column Data

Here we have two options

1. type possible values are(action, ..., url);
2. typeAttributes value depends on the type option value like for url we have (label, target);

Here is the example of the same: lightning:datatable

Below is the example of the options:

And we can also do this type adjustment just before assigning the columns settings to the attribute in the helper(if not want to do in the Apex):

({
  getLightningTableData: function (component) {
    var recLimit = component.get('v.recLimit');
    var sColumn = component.get('v.fields');
    var sObject = component.get('v.object');
    var action = component.get('c.getsObjectRecords');
    action.setParams({
      ObjectName: sObject,
      fieldstoget: sColumn,
      recLimit: recLimit
    });
    action.setCallback(this, function (response) {
      var state = response.getState();
      if (state === 'SUCCESS') {
        var rtnValue = response.getReturnValue();

        rtnValue.tableColumn.forEach(function (column) {
          switch (column.fieldName) {
            case 'Show_Record__c':
              column.type = 'url';
              column['typeAttributes'] = { label: { fieldName: 'Name' } };
              break;

            default:
              break;
          }
        });

        component.set('v.mycolumn', rtnValue.tableColumn);
        component.set('v.mydata', rtnValue.tableRecord);
      }
    });
    $A.enqueueAction(action);
  },
  /* more methods */
})
