如何在CKEditor中为两个不同的组提供两个不同的工具栏？

<!-- CKEditor实例1 -->
<textarea name="editor1"></textarea>
<script>
    CKEDITOR.replace('editor1', {
        toolbar: [
            { name: 'document', items: ['Source', '-', 'Save', 'NewPage', 'Preview', 'Print', '-', 'Templates'] },
            { name: 'clipboard', items: ['Cut', 'Copy', 'Paste', 'PasteText', 'PasteFromWord', '-', 'Undo', 'Redo'] },
            { name: 'editing', items: ['Find', 'Replace', '-', 'SelectAll', '-', 'Scayt'] },
            { name: 'insert', items: ['Image', 'Flash', 'Table', 'HorizontalRule', 'Smiley', 'SpecialChar', 'PageBreak', 'Iframe'] },
            '/',
            { name: 'styles', items: ['Styles', 'Format'] },
            { name: 'basicstyles', items: ['Bold', 'Italic', 'Underline', 'Strike', 'Subscript', 'Superscript', '-', 'RemoveFormat'] },
            { name: 'paragraph', items: ['NumberedList', 'BulletedList', '-', 'Outdent', 'Indent', '-', 'Blockquote', 'CreateDiv', '-', 'JustifyLeft', 'JustifyCenter', 'JustifyRight', 'JustifyBlock', '-', 'BidiLtr', 'BidiRtl'] },
            { name: 'links', items: ['Link', 'Unlink', 'Anchor'] },
            { name: 'tools', items: ['Maximize', 'ShowBlocks'] },
            { name: 'others', items: ['-'] },
            { name: 'about', items: ['About'] }
        ]
    });
</script>

<!-- CKEditor实例2 -->
<textarea name="editor2"></textarea>
<script>
    CKEDITOR.replace('editor2', {
        toolbar: [
            { name: 'document', items: ['Source', '-', 'Save', 'NewPage', 'Preview', 'Print', '-', 'Templates'] },
            { name: 'clipboard', items: ['Cut', 'Copy', 'Paste', 'PasteText', 'PasteFromWord', '-', 'Undo', 'Redo'] },
            { name: 'editing', items: ['Find', 'Replace', '-', 'SelectAll', '-', 'Scayt'] },
            { name: 'insert', items: ['Image', 'Table', 'HorizontalRule', 'SpecialChar', 'PageBreak', 'Iframe'] },
            '/',
            { name: 'styles', items: ['Styles', 'Format'] },
            { name: 'basicstyles', items: ['Bold', 'Italic', 'Underline', 'Strike', 'Subscript', 'Superscript', '-', 'RemoveFormat'] },
            { name: 'paragraph', items: ['NumberedList', 'BulletedList', '-', 'Outdent', 'Indent', '-', 'Blockquote', 'CreateDiv', '-', 'JustifyLeft', 'JustifyCenter', 'JustifyRight', 'JustifyBlock', '-', 'BidiLtr', 'BidiRtl'] },
            { name: 'links', items: ['Link', 'Unlink', 'Anchor'] },
            { name: 'tools', items: ['Maximize', 'ShowBlocks'] },
            { name: 'others', items: ['-'] },
            { name: 'about', items: ['About'] }
        ]
    });
</script>
