JavaScript 数据转换：将数组转换为树形结构

var data = [ { name: 'A站点', children: [ { key: 'pressureIn', name: '出口压力', minWidth: 90 }, { key: 'pressureOut', name: '入口压力', minWidth: 95 } ] }, { name: 'B站点', children: [ { key: 'pressure', name: '出口压力', minWidth: 90 }, { key: 'flow', name: '进水压力', minWidth: 95 } ] } ];
