ivew table列表里 render button 修改单个的样式或者禁用或者隐藏

很简单废话不多说，看代码： 

h('a', { props: { }, attrs: { //按钮禁用 disabled: params.row.pdf?false:true, href: `/pdf/${params.row.tiaoma}-${params.row.rep_id}.pdf`, download: `${params.row.tiaoma}-${params.row.rep_id}.pdf`, }, style: { display:"inline-block", color: params.row.pdf?"#68B2FE":"#ccc", margin:"5px", //按钮隐藏 display:params.row.pdf?'inline-block': 'none', }, on: { click: (e) => { this.seeReport(e, params.row.id, params.row.pdf); } } }, '查看PDF报告'),
