Successfully generates docs for the following code: ```js /** * A table object * @param {number} width * @param {number} height */ class Table { constructor(width, height) { this.width = width; this.height = height; } } ``` But, just adding a `require` statement results that it couldn't generate docs for the Table class. ```js const _ = require('lodash') /** * A table object * @param {number} width * @param {number} height */ class Table { constructor(width, height) { this.width = width; this.height = height; } } ``` How can I fix this problem?
