xlsx-style 说明文档

0.单元格样式:

样式属性	子属性	取值
fill	patternType	`"solid"` or `"none"`
	fgColor	`COLOR_SPEC`
	bgColor	`COLOR_SPEC`
font	name	`"Calibri"` // default
	sz	`"11"` // font size in points
	color	`COLOR_SPEC`
	bold	`true` or `false`
	underline	`true` or `false`
	italic	`true` or `false`
	strike	`true` or `false`
	outline	`true` or `false`
	shadow	`true` or `false`
	vertAlign	`true` or `false`
numFmt		`"0"` // integer index to built in formats, see StyleBuilder.SSF property
		`"0.00%"` // string matching a built-in format, see StyleBuilder.SSF
		`"0.0%"` // string specifying a custom format
		`"0.00%;\\(0.00%\\);\\-;@"` // string specifying a custom format, escaping special characters
		`"m/dd/yy"` // string a date format using Excel's format notation
alignment	vertical	`"bottom"` or `"center"` or `"top"`
	horizontal	`"bottom"` or `"center"` or `"top"`
	wrapText	`true` or `false`
	readingOrder	`2` // for right-to-left
	textRotation	Number from `0` to `180` or `255` (default is `0`)
		`90` is rotated up 90 degrees
		`45` is rotated up 45 degrees
		`135` is rotated down 45 degrees
		`180` is rotated down 180 degrees
		`255` is special, aligned vertically
border	top	`{ style: BORDER_STYLE, color: COLOR_SPEC }`
	bottom	`{ style: BORDER_STYLE, color: COLOR_SPEC }`
	left	`{ style: BORDER_STYLE, color: COLOR_SPEC }`
	right	`{ style: BORDER_STYLE, color: COLOR_SPEC }`
	diagonal	`{ style: BORDER_STYLE, color: COLOR_SPEC }`
	diagonalUp	`true` or `false`
	diagonalDown	`true` or `false`

1.下载xlsx-style

npm install xlsx-style

xlsx-style核心模块在 你安装路径\node_modules\xlsx-style\dist

2.示例代码

复制出文件xlsx.full.min.js

编写示例代码:


<!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;

            }
        }
    </script>
    <button onclick="downloadExl(jsono)">导出</button>
