Answer 1

使用

echo ExportMenu::widget([

    'columnBatchToggleSettings'=>['label'=>'Alle Wählen'],

    'dropdownOptions' => 
    [
       'label' => 'Exportieren',
       'class' => 'btn btn-wkm'
    ],

    'columnSelectorOptions'=>
    [
       'label' => 'Exportspalten',
       'class' => 'btn btn-default dropdown-toggle',
       'scrollable'=> true,
    ],

    'columnSelectorMenuOptions' => 
    [
        'class' => 'dropdown-menu scrollable-menu',
        'role'=> 'menu'
    ],

   'dataProvider' => $dataProviderClone,
   'columns' => $gridColumns,

   'exportConfig' =>
    [
       ExportMenu::FORMAT_TEXT => false,
       ExportMenu::FORMAT_HTML => false,
       ExportMenu::FORMAT_EXCEL => false,
       ExportMenu::FORMAT_PDF => false,

       ExportMenu::FORMAT_EXCEL_X => 
       [
         'label' => 'EXCEL',
       ]
    ],

    'container'=>['class'=>'btn-group pull-left', 'style'=> 'margin: 5px']
]);

例如

replace(/,\n/g,"")
