涉及到合并单元+去网格线+总列数不固定的情况
使用的是xlsx文档，使用方法等同于SheetJS中文文档 。

最终效果

步骤1：安装xlsx及xlsx
cnpm install xlsx --save
cnpm install xlsx-style --save
image.png
步骤2：修改xlsx-style插件包的代码
- 修改1：找到 node_modules-----> xlsx-style---->dist---->cpexcel.js
807行将
var cpt = require('./cpt' + 'able');改为var cpt = cptable;
image.png
- 修改2：找到 node_modules-----> xlsx-style---->ods.js
10行将
return require('../' + 'xlsx').utils;改为return require('./' + 'xlsx').utils;
image.png
- 修改3：如果你的excel想要设置行高功能的话，xlsx-style是无法设置的，但是该功能xlsx是有的，因此将相关功能代码复制粘贴到xlsx-style中就可以让使其具有设置行高的功能。
找到xlsx下的xlsx.js,复制如下两个截图代码到xlsx-style下的xlsx.js中
var DEF_PPI = 96, PPI = DEF_PPI;
function px2pt(px) { return px * 96 / PPI; }
function write_ws_xml_data(ws, opts, idx, wb) {
var o = [], r = [], range = safe_decode_range(ws['!ref']), cell="", ref, rr = "", cols = [], R=0, C=0, rows = ws['!rows'];
var dense = Array.isArray(ws);
var params = ({r:rr}), row, height = -1;
for(C = range.s.c; C <= range.e.c; ++C) cols[C] = encode_col(C);
for(R = range.s.r; R <= range.e.r; ++R) {
r = [];
rr = encode_row(R);
for(C = range.s.c; C <= range.e.c; ++C) {
ref = cols[C] + rr;
var _cell = dense ? (ws[R]||[])[C]: ws[ref];
if(_cell === undefined) continue;
if((cell = write_ws_xml_cell(_cell, ref, ws, opts, idx, wb)) != null) r.push(cell);
}
if(r.length > 0 || (rows && rows[R])) {
params = ({r:rr});
if(rows && rows[R]) {
row = rows[R];
if(row.hidden) params.hidden = 1;
height = -1;
if(row.hpx) height = px2pt(row.hpx);
else if(row.hpt) height = row.hpt;
if(height > -1) { params.ht = height; params.customHeight = 1; }
if(row.level) { params.outlineLevel = row.level; }
}
o[o.length] = (writextag('row', r.join(""), params));
}
}
if(rows) for(; R < rows.length; ++R) {
if(rows && rows[R]) {
params = ({r:R+1});
row = rows[R];
if(row.hidden) params.hidden = 1;
height = -1;
if (row.hpx) height = px2pt(row.hpx);
else if (row.hpt) height = row.hpt;
if (height > -1) { params.ht = height; params.customHeight = 1; }
if (row.level) { params.outlineLevel = row.level; }
o[o.length] = (writextag('row', "", params));
}
}
return o.join("");
