node 使用第三方api 生成 word 文档之修改源码实现需求

使用了 officegen 第三方 api 实现生成word 文档，但是发现下划线无法满足需求。修改源码以便后人踩坑,以下是我的一个demo，通过传参数设置下划线颜色以及高度。本demo 通过json 配置方式，还有api 调用方式实现方式，详细可以参考git 的例子
GITHUB Api地址: https://github.com/Ziv-Barber/officegen

var officegen = require('officegen');
var fs = require('fs');
var path = require('path');
var docx = officegen('docx');

var header = docx.getHeader().createP({
    align: ('center')
});

console.log('路徑為' + __dirname);

docx.createByJson(data)

//var pObj = docx.createTable(table, tableStyle);
var out = fs.createWriteStream('out.docx'); // 文件写入
out.on('error', function(err) {
    console.log(err);
});
var result = docx.generate(out);

找到源码修改

修改代码部分如下：gendocx.js 部分

 else if ( objs_list[i].data[j].horizontal_line ) {
                        console.log(objs_list[i].data[j]);
                        var height=typeof objs_list[i].data[j].options.height=="string"?objs_list[i].data[j].options.height:".75";
                        var fillcolor=typeof objs_list[i].data[j].options.fillcolor=="string"?objs_list[i].data[j].options.fillcolor:"e0e0e0";
                        //outString += ``;
                        outString += ``;
                    // Bookmark start support:
                    }

docx-p.js 部分

MakeDocxP.prototype.addHorizontalLine = function (opt) {
    var newP = this;
    newP.data[newP.data.length] = { 'horizontal_line': true, options:opt||{} };
};

修改为传参数设置其下滑线颜色跟高度最后附上效果图：
