	Constructs an empty table with at least `n` buckets, using `a` and default hash function and key equality predicate, and inserts the elements from `il` into it.	构造一个至少包含 n 个桶的空表，使用分配器 a 以及默认哈希函数、键相等谓词，并将 il 中的元素插入表中。

Destroys previously existing elements, swaps the hash function and predicate from `other`, and move-assigns the allocator from `other` if `Alloc::propagate_on_container_move_assignment` exists and `Alloc::propagate_on_container_move_assignment::value` is `true`.

	If an element `x` exists with key equivalent to `k`, invokes `f` with a reference to `x`. Such reference is const iff `*this` is const.	若存在键与 k 等价的元素 x，则以 x 的引用调用函数 f。当且仅当当前容器 *this 为常量（const）时，该引用为常量引用。
