如何让 will_paginate 正确显示条目数？

gem 'will_paginate'

@posts = Post.paginate(page: params[:page], per_page: 10)

<%= will_paginate @posts %>

.pagination {
  display: inline-block;
  margin: 0;
  padding: 0;
}

.pagination a,
.pagination span {
  display: inline-block;
  padding: 0.5em 1em;
  margin: 0 0.25em;
  text-decoration: none;
  border: 1px solid #ccc;
  border-radius: 4px;
}

.pagination a:hover {
  background-color: #f5f5f5;
}

.pagination .current {
  background-color: #007bff;
  color: #fff;
  border: 1px solid #007bff;
}
