You just need add a new column in grid (Areas\Admin\Views\Vendor\List.cshtml).
For example:
columns: [{
field: "Id",
title: "Vendor Id",
width: 300
}, {
field: "Name",
title: "@T("Admin.Vendors.Fields.Name")",
width: 300
}, {
field: "Email",
title: "@T("Admin.Vendors.Fields.Email")",
width: 300
}, {
field: "Active",
title: "@T("Admin.Vendors.Fields.Active")",
width: 100,
headerAttributes: { style: "text-align:center" },
attributes: { style: "text-align:center" },
template: '# if(Active) {# <i class="fa fa-check true-icon"></i> #} else {# <i class="fa fa-close false-icon"></i> #} #'
}, {
field: "Id",
title: "@T("Admin.Common.Edit")",
width: 100,
headerAttributes: { style: "text-align:center" },
attributes: { style: "text-align:center" },
template: '<a class="btn btn-default" href="Edit/#=Id#"><i class="fa fa-pencil"></i>@T("Admin.Common.Edit")</a>'}]
