This time I will show you how to use the cell style of js-xlsx, and what are the precautions for using the cell style of js-xlsx. The following is a practical case, let's take a look.
Download xlsx-stylenpm install xlsx-style2. Sample codeCopy the file xlsx.full.min.jsWrite the sample code:
<!DOCTYPE html><html><head> <meta charset="UTF-8"> <title>示例</title></head><body> <script src="./xlsx.full.min.js"></script> <script> function saveAs(obj, fileName) { var tmpa = document.createElement("a"); tmpa.download = fileName || "下载"; tmpa.href = URL.createObjectURL(obj); tmpa.click(); setTimeout(function () { URL.revokeObjectURL(obj); }, 100); } var jsono = [{ "id": 1, "合并的列头1": "数据11", "合并的列头2": "数据12", "合并的列头3": "数据13", "合并的列头4": "数据14", }, { "id": 2, "合并的列头1": "数据21", "合并的列头2": "数据22", "合并的列头3": "数据23", "合并的列头4": "数据24", }]; const wopts = { bookType: 'xlsx', bookSST: true, type: 'binary', cellStyles: true }; function downloadExl(json, type) { var tmpdata = json[0]; json.unshift({}); var keyMap = []; //获取keys for (var k in tmpdata) { keyMap.push(k); json[0][k] = k; } var tmpdata = [];//用来保存转换好的json json.map((v, i) => keyMap.map((k, j) => Object.assign({}, { v: v[k], position: (j > 25 ? getCharCol(j) : String.fromCharCode(65 + j)) + (i + 1) }))).reduce((prev, next) => prev.concat(next)).forEach((v, i) => tmpdata[v.position] = { v: v.v }); var outputPos = Object.keys(tmpdata); //设置区域,比如表格从A1到D10 tmpdata["B1"].s = { font: { sz: 14, bold: true, color: { rgb: "FFFFAA00" } }, fill: { bgColor: { indexed: 64 }, fgColor: { rgb: "FFFF00" } } };//<====设置xlsx单元格样式 tmpdata["!merges"] = [{ s: { c: 1, r: 0 }, e: { c: 4, r: 0 } }];//<====合并单元格 var tmpWB = { SheetNames: ['mySheet'], //保存的表标题 Sheets: { 'mySheet': Object.assign({}, tmpdata, //内容 { '!ref': outputPos[0] + ':' + outputPos[outputPos.length - 1] //设置填充区域 }) } }; tmpDown = new Blob([s2ab(XLSX.write(tmpWB, { bookType: (type == undefined ? 'xlsx' : type), bookSST: false, type: 'binary' }//这里的数据是用来定义导出的格式类型 ))], { type: "" }); saveAs(tmpDown, "这里是下载的文件名" + '.' + (wopts.bookType == "biff2" ? "xls" : wopts.bookType)); } function getCharCol(n) { let temCol = '', s = '', m = 0 while (n > 0) { m = n % 26 + 1 s = String.fromCharCode(m + 64) + s n = (n - m) / 26 } return s } function s2ab(s) { if (typeof ArrayBuffer !== 'undefined') { var buf = new ArrayBuffer(s.length); var view = new Uint8Array(buf); for (var i = 0; i != s.length; ++i) view[i] = s.charCodeAt(i) & 0xFF; return buf; } else { var buf = new Array(s.length); for (var i = 0; i != s.length; ++i) buf[i] = s.charCodeAt(i) & 0xFF; return buf; } } </script> <button onclick="downloadExl(jsono)">导出</button></body></html>I believe you have mastered the method after reading the case in this article , for more exciting content, please pay attention to other related articles on the php Chinese website!

JavaScript originated in 1995 and was created by Brandon Ike, and realized the language into C. 1.C language provides high performance and system-level programming capabilities for JavaScript. 2. JavaScript's memory management and performance optimization rely on C language. 3. The cross-platform feature of C language helps JavaScript run efficiently on different operating systems.

JavaScript runs in browsers and Node.js environments and relies on the JavaScript engine to parse and execute code. 1) Generate abstract syntax tree (AST) in the parsing stage; 2) convert AST into bytecode or machine code in the compilation stage; 3) execute the compiled code in the execution stage.

The future trends of Python and JavaScript include: 1. Python will consolidate its position in the fields of scientific computing and AI, 2. JavaScript will promote the development of web technology, 3. Cross-platform development will become a hot topic, and 4. Performance optimization will be the focus. Both will continue to expand application scenarios in their respective fields and make more breakthroughs in performance.

Both Python and JavaScript's choices in development environments are important. 1) Python's development environment includes PyCharm, JupyterNotebook and Anaconda, which are suitable for data science and rapid prototyping. 2) The development environment of JavaScript includes Node.js, VSCode and Webpack, which are suitable for front-end and back-end development. Choosing the right tools according to project needs can improve development efficiency and project success rate.

Yes, the engine core of JavaScript is written in C. 1) The C language provides efficient performance and underlying control, which is suitable for the development of JavaScript engine. 2) Taking the V8 engine as an example, its core is written in C, combining the efficiency and object-oriented characteristics of C. 3) The working principle of the JavaScript engine includes parsing, compiling and execution, and the C language plays a key role in these processes.

JavaScript is at the heart of modern websites because it enhances the interactivity and dynamicity of web pages. 1) It allows to change content without refreshing the page, 2) manipulate web pages through DOMAPI, 3) support complex interactive effects such as animation and drag-and-drop, 4) optimize performance and best practices to improve user experience.

C and JavaScript achieve interoperability through WebAssembly. 1) C code is compiled into WebAssembly module and introduced into JavaScript environment to enhance computing power. 2) In game development, C handles physics engines and graphics rendering, and JavaScript is responsible for game logic and user interface.

JavaScript is widely used in websites, mobile applications, desktop applications and server-side programming. 1) In website development, JavaScript operates DOM together with HTML and CSS to achieve dynamic effects and supports frameworks such as jQuery and React. 2) Through ReactNative and Ionic, JavaScript is used to develop cross-platform mobile applications. 3) The Electron framework enables JavaScript to build desktop applications. 4) Node.js allows JavaScript to run on the server side and supports high concurrent requests.
