Documentation 如何使用jsdoc记录模块内的函数？

我试过了，但是html页面只显示lib/help，然后是空白页面。我还想使用@exports来说明模块导出的内容。还有一种方法可以在JSDoc中记录对象的用途和概述。

JSDoc注释块应该在声明之前

/**
* Displays the list of autolab commands along with their functions.
* @module lib/help
*/
var Table = require('cli-table');
var chalk = require('chalk');
var helpjson = {
    'init'              : 'Initializes local repository and authenticates',
    'exit'              : 'Wipes off the credentials from the system',
    'git create'        : 'Creates a repository on Gitlab',
    'git delete'        : 'Deletes the specified repository from Gitlab',
    'git changeserver'  : 'To change the host of Gitlab',
    'git changelang'    : 'To change the language of the code submission',
    'git push'          : 'Adds, commits, pushes the code',
    'submit'            : 'To submit the code to JavaAutolab and fetch the results',
    'help'              : 'Print help manual'
};
module.exports = function() {
    /**
    * Displays the list of autolab commands along with their functions.
    * @function
    * @param {null}
    */
    console.log('\n' + chalk.blue('Usage:') + ' autolab [OPTIONS]');
    var table = new Table({
        head: ['Options:', ''],
        colWidths: [20,70]
    });
    for (var key in helpjson)
    table.push(
        [key,helpjson[key]]
        );
    console.log(table.toString());
};

还有一种方法可以在JSDoc中记录对象的用途和概述吗

标记提供文件的说明。在文件开头的JSDoc注释中使用标记

通过阅读更多的文档来熟悉

    /**

    var chalk = require('chalk');

    module.exports = function () {

        var table = new Table({

            colWidths: [20, 70]
        });
        for (var key in helpjson)
            table.push(
