添加行方法

	// 添加行的索引
	tableRowClassName ({row, rowIndex}) {
		row.index = rowIndex
		console.log('row.index: ' + row.index)
	}

删除行方法

	// 行点击消除new标记
	onRowClick (row, event, column) {
		this.currentRow = row.index
		console.log('row.index----' + this.currentRow)
	},
	// 删除单行表格数据
	delGrid () {
		let index = this.currentRow
		console.log('index: ------------' + index)
		if (index === null) {
			this.$alert('请选中要删除的记录！', '消息', {
				dangerouslyUseHTMLString: true,
				type: 'warning'
   			 })
		} else {
			this.formData.dataList.splice(index, 1)
			this.$alert('删除成功！', '消息', {
				dangerouslyUseHTMLString: true,
				type: 'success'
			})
		}
