<div ng-class="{ 'sortable': sortable }">
<!-- <div class="ui-grid-vertical-bar"> </div> -->
<div class="ui-grid-cell-contents" col-index="renderIndex" title="TOOLTIP">
<span>{{ col.displayName CUSTOM_FILTERS }}</span>
<span ui-grid-visible="col.sort.direction" ng-class="{ 'ui-grid-icon-up-dir': col.sort.direction == asc,'ui-grid-icon-down-dir': col.sort.direction == desc,'ui-grid-icon-blank': !col.sort.direction }">
</span>
</div>
<div class="ui-grid-column-menu-button" ng-if="grid.options.enableColumnMenus && !col.isRowHeader && col.colDef.enableColumnMenu !== false" ng-click="toggleMenu($event)" ng-class="{'ui-grid-column-menu-button-last-col': isLastCol}">
