ligerui 行合并

ligerui 行合并2019独角兽企业重金招聘Python工程师标准>>>…

大家好,欢迎来到IT知识分享网。

在项目中使用到ligerui 的grid 需要行合并实现的效果如图所示

在网上找了几天文章,相对来讲,效果不是太好,怎么办,直接扩展

$.extend($.ligerui.controls.Grid.prototype, {

            gridhtmlarr.push('</tr>');
        }
        return gridhtmlarr.join('');
    }
});

扩展思路,重写 grid 的 _getHtmlFromData 方法,计算只要相同的内容就自动合并。

这个时候页面上面怎么用呢,亲们看好啦,非常简单,只需要在需要合并的列上面加上rowSpan:true 即可,很简单的有么有

{display: '行政区', name: 'cantonName', align: 'center', width: 150, minWidth: 60, frozen: true,rowSpan:true},
{display: '企业名称', name: 'NAME', align: 'center', width: 150, minWidth: 60, frozen: true,rowSpan:true},
