I need to hide the View button inside Lightning Datatable based on Team Group Name in that same row 


If team Group name is blank then view button must be hidden and if team group name is not blank then i need to show view button
Here is my code:
columns: [ {label: "Course Title", fieldName: "CourseTitle", type: "text"}, {label: "Team Group Name", fieldName: "TeamGroupName", type: "text"}, {label: "Campus Name", fieldName: "CampusName", type: "text"}, {label: "Course", fieldName: "Course", type: "text"}, {label: "Section ID", fieldName: "SectionID", type: "text"}, {label: "Session", fieldName: "Session", type: "text"}, {label: "Course Level", fieldName: "CourseLevel", type: "text"}, {label: "Term Length", fieldName: "TermLength", type: "text"}, {type: "button", typeAttributes: { label: 'View', name: 'View', title: 'View', disabled: false, value: 'view', iconPosition: 'left' }} ]
Component:
<aura:component implements="force:appHostable" controller="Teams_Controller"> <aura:attribute type="Account[]" name="acctList"/> <aura:attribute name="mycolumns" type="List"/> <aura:handler name="init" value="{!this}" action="{!c.fetchAccounts}"/> <lightning:datatable data="{! v.acctList }" columns="{! v.mycolumns }" keyField="id" hideCheckboxColumn="false" onrowaction="{!c.viewRecord}"/>
