cell-cursor="expression"

bind cell-cursor. export CellCursor object.

  <div ng-init="items=[{id:1,name:'apple'},{id:2,name:'orange'},{id:3,name:'banana'}]">
    <!-- bind CellCursor to scope.x -->
    <!-- table need tablindex attribute for directive catch keydown events. -->
    <table tabindex="0" cell-cursor="x">
    	<tbody><!-- cursor can move in tbody -->
	    	<tr ng-repeat="i in items">
	    		<td>{{i.id}}</td>
	    		<td>{{i.name}}</td>
	    	</tr>
	    </tbody>
    </table>
    <!-- you can access CellCursor Object -->
    cursor=[{{x.selected.cursor.row}},{{x.selected.cursor.col}}]
  </div>

cell-cursor-copy

cell-cursor-copy="expression"

When copy called, then set data to clipboard.

  <div ng-app="app" ng-controller="rootCtrl">
    <table tabindex="0" cell-cursor="x" cell-cursor-copy="x.getSelectedCellValues()|cellCursorToTsv">
    	<tbody>
	    	<tr ng-repeat="i in items">
	    		<!-- if you use ng-model on `td`, getSelectedCellValues() get data by ngModelControll.$viewValue -->
	    		<td ng-model="i.id">{{i.id}}</td>
	    		<!-- if you use cell-options on `td`, getSelectedCellValues() get data by getter() -->
	    		<td cell-cursor-options="{getter:getName(i)}">{{i.name}}</td>
	    	</tr>
	    </tbody>
    </table>
  </div>
  <script>
  angular.module('app',['cellCursor'])
  .controller('rootCtrl',['$scope',function($scope){
    $scope.items=[{id:1,name:'apple'},{id:2,name:'orange'},{id:3,name:'banana'}];
		// create getter
		$scope.getName=function(i){
			return function(){
				return "["+i.name+"]";
			}
		}	
	}]);
	</script>

cell-cursor-paste

cell-cursor-paste="expression"

When press ctrl+v called, then get data from clipboard.

Expression scope has $data it is clipboard data.

  <div ng-app="app" ng-controller="rootCtrl">
    <table tabindex="0" cell-cursor="x" cell-cursor-paste="x.setSelectedCellValues($data)">
    	<tbody>
	    	<tr ng-repeat="i in items">
	    		<!-- if you use ng-model on `td`, setSelectedCellValues() set data by ngModelControll.$setViewValue -->
	    		<!-- if td has readonly attributes, setSelectedCellValues dose not effect -->
	    		<td ng-model="i.id" ng-readonly="readonly">{{i.id}}</td>
	    		<!-- if you use cell-options on `td`, setSelectedCellValues() set data by setter() -->
	    		<td cell-cursor-options="{setter:setName(i)}">{{i.name}}</td>
	    	</tr>
	    </tbody>
    </table>
    <button ng-click="readonly=!readonly">readonly({{readonly}})</button>
  </div>
  <script>
  angular.module('app',['cellCursor'])
  .controller('rootCtrl',['$scope',function($scope){
    $scope.items=[{id:1,name:'apple'},{id:2,name:'orange'},{id:3,name:'banana'}];
		// create setter
		$scope.setName=function(i){
			return function(v){
				if(v!="badname"){
					return i.name=v;
				}
			}
		}
	}]);
	</script>

cell-cursor-options

cell-cursor-options="expression"

set option object. set to cell( td or th ) element.

{
  "setter":"function: cell value setter",
  "getter":"function: cell value getter",
  "model":"string: expression for bind value in scope",
  "input":"string: querySelector for input element(that has ngModel)",
  "editor":"string: editor type name. it defined by cellCursorEditorFactory service",
  "on[event]":"function: called on events"
}

Order　of　getters/setter definitions is getter|setter > bind > ngModel > input.

Event function signeture is function (event, option:(cell-cursor-options), cellCursorOptionsController, cellCursor, td:HTMLCellElement):boolean.

event called now keydown|keypress|keydown|compositionstart|compositionupdate|compositionend|input only.

  <div ng-init="items=[{name:'apple'},{name:'orange'},{name:'banana'}]">
    <table cell-cursor="x">
    	<tr ng-repeat="i in items"><td cell-cursor-options="{model:'i.name',editor:'text'}">{{i.name}}</td></tr>
    </table>
  </div>

cell-cursor-drag

cell-cursor-drag="expression"

    <table tabindex="0" cell-cursor="x">
      <tbody>
        <tr ng-repeat="i in items">
          <td ng-model="i.id" ng-readonly="readonly" cell-cursor-drag="x">{{i.name}}</td>
        </tr>
      </tbody>
    </table>
  </div>
  <script>
  angular.module('app',['cellCursor'])
  .controller('rootCtrl',['$scope',function($scope){
    $scope.items=[{id:1,name:'apple'},{id:2,name:'orange'},{id:3,name:'banana'}];
    // after initialized handler
    $scope.$on("cellCursor",function(e, cellCursor, name){
      if(name=='x'){
        // set drag handler
        cellCursor.$on("cellCursor.drag",function(e, fromPos, toPos){
          if(fromPos.row!=toPos.row){
            // cut & paste
            var s = $scope.items.splice(fromPos.row,1);
            $scope.items.splice.apply($scope.items,[toPos.row,0].concat(s));
            fromPos.row = toPos.row;
          }else{
            e.preventDefault();
          }
        });
      }
