Interior columns supported a roof and a second story which let in light.

内部的柱子支撑着屋顶和第二层楼， 让光线透进来。

There would be no interior columns in the office spaces, an amazing feat as there would be 40 000 square feet of office space on each of the upper floors.

办公空间将没有内部柱子，这是一个了不起的壮举，因为每层楼上都有 40 000 平方英尺的办公空间。
