Hi All,
I am using lightning:datatable and my column value is getting truncate by default. I am not able to avoid it 
Below is my code for reference
       <lightning:datatable data="{! v.mydata }" 
                             columns="{! v.mycolumns }" 
                             keyField="id"
                             onrowselection="{! c.getSelectedName }"
                            />
Any help is appreciated. 

Has anybody completed challenge 5 in lightning experience superbadge? If yes kindly post the solution of the same.
I'm facing problem in the following section.
Awaiting Approval
If the status changes to awaiting approval and there is a positive discount value, kick off the discount approval process. If no discount is applied, the status updates to Scheduled because no approval is needed when a package is purchased at full price.

It is showing me the following error.


Kindly share the solution.
