<p>给你一个数组 <code>orders</code>,表示客户在餐厅中完成的订单,确切地说, <code>orders[i]=[customerName<sub>i</sub>,tableNumber<sub>i</sub>,foodItem<sub>i</sub>]</code> ,其中 <code>customerName<sub>i</sub></code> 是客户的姓名,<code>tableNumber<sub>i</sub></code> 是客户所在餐桌的桌号,而 <code>foodItem<sub>i</sub></code> 是客户点的餐品名称。</p>
|
||
|
||
<p>请你返回该餐厅的 <strong>点菜展示表</strong><em> 。</em>在这张表中,表中第一行为标题,其第一列为餐桌桌号 “Table” ,后面每一列都是按字母顺序排列的餐品名称。接下来每一行中的项则表示每张餐桌订购的相应餐品数量,第一列应当填对应的桌号,后面依次填写下单的餐品数量。</p>
|
||
|
||
<p>注意:客户姓名不是点菜展示表的一部分。此外,表中的数据行应该按餐桌桌号升序排列。</p>
