如何使用ckEditor在文本区域中定义cols，在许多站点中读取并找不到答案。我把隐式代码放了，但它不起作用。

<textarea id="ckEditor" name="ckEditor" rows="25" cols="30" ></textarea>
Config.js
CKEDITOR.editorConfig = function( config ) {
// Define changes to default configuration here. For example:
// config.language = 'fr';
// config.uiColor = '#AADC6E';
config.allowedContent = true;
config.extraPlugins = 'imprimirdoc';
config.toolbar = [{name: 'styles', items:['Font','FontSize']},{name: 'basicstyles', items: ['Bold', 'Italic','Underline']},['Cut', 'Copy', 'Paste', 'PasteText', 'PasteFromWord','-', 'Undo', 'Redo'],{name: 'document', items:['imprimirdoc','Preview']},{name: 'editing', items: ['Find','SelectAll','-','Scayt']},'/',
{name: 'paragraph', items:['NumberedList','BulletedList','-','Outdent', 'Indent', '-', 'Blockquote','-', 'JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock','BidiLtr','BidiRtl' ]},
{name: 'insert', items:['Table','HorizontalRule','SpecialChar', 'PageBreak']},
{name: 'colors', items:['TextColor', 'BGColor']},
{name: 'tools', items: [ 'Maximize']}];
config.pasteFromWordRemoveStyles = false;
config.contentsCss = ['contents.css'];
config.cols = 10;
