extjs4 - 报表内容可选中复制
添加CSS：
/* make table selectable and copyable */
.x-grid-row ,.x-grid-cell, .x-unselectable, .x-unselectable * {
-webkit-user-select: text !important;
-o-user-select: text !important;
-khtml-user-select: all !important;
-ms-user-select: text !important;
user-select: text !important;
-moz-user-select: text !important;
}
然后在JS中：
/* make grid content selectable and copyable */
if(typeof Ext != 'undefined'){
Ext.core.Element.prototype.unselectable = function(){return this;};
Ext.view.TableChunker.metaRowTpl = [
'<tr class="' + Ext.baseCSSPrefix + 'grid-row {addlSelector} {[this.embedRowCls()]}" {[this.embedRowAttr()]}>',
'<tpl for="columns">',
'<td class="{cls} ' + Ext.baseCSSPrefix + 'grid-cell ' + Ext.baseCSSPrefix + 'grid-cell-{columnId} {{id}-modified} {{id}-tdCls} {[this.firstOrLastCls(xindex, xcount)]}" {{id}-tdAttr}><div class="' + Ext.baseCSSPrefix + 'grid-cell-inner ' + Ext.baseCSSPrefix + 'unselectable" style="{{id}-style}; text-align: {align};">{{id}}</div></td>',
'</tpl>',
'</tr>'
];
}
