Idea general, organízala cuando estés libre
Este método consiste en tener primero la plantilla de Word y luego reemplazar el contenido en la plantilla. El contenido de la plantilla se divide en 2 bloques, uno está en el párrafo y el otro es el formulario que debe generarse dinámicamente, por lo que hay también dos métodos de fondo
1: Método en segundo plano (este método está organizado para Baidu)
