Exceljs使用

第一部分 下载

npm install exceljs

第二部分 基本的配置

var Excel = require("exceljs");

var workbook = new Excel.Workbook();

// 基本的创建信息
workbook.creator = "Me";
workbook.lastModifiedBy = "Her";
workbook.created = new Date(1985, 8, 30);
workbook.modified = new Date();
workbook.lastPrinted = new Date(2016, 9, 27);

// 视图大小， 打开Excel时，整个框的位置，大小
workbook.views = [
    {
        x: 0,
        y: 0,
         1000,
        height: 2000,
        firstSheet: 0,
        activeTab: 1,
        visibility: "visible"
    }
];

// 标签创建
var worksheet = workbook.addWorksheet("第一个标签");
  // 带颜色的
var worksheet2 = workbook.addWorksheet("第二个标签", { properties: { tabColor: { argb: "FFC0000" } } });

// 遍历标签
workbook.eachSheet((worksheet, sheetId) => {
    console.log("标签ID：", sheetId)
})
// console.log(worksheet);
// 删除一个标签
workbook.removeWorksheet(2)

var firstSheet = workbook.getWorksheet(1);
console.log("标签信息-id", firstSheet.id);
console.log("获取总的：行/实际行 /列/实际列 个数： ", firstSheet.rowCount, firstSheet.actualColumnCount, firstSheet.columnCount, firstSheet.actualColumnCount);

// 添加那个筛选箭头
worksheet.autoFilter = 'A1:C1';

worksheet.getRow(5).font = { size: 14, bold: true };

worksheet.getCell("A2").value = "Site";
worksheet.getCell("A2").font = {
    name: "Arial Black",
    color: { argb: "FF00FF00" },
    family: 2,
    size: 14,
    italic: true,
    bold: true
};

// save workbook to disk
workbook.xlsx.writeFile("first.xlsx").then(function() {
    console.log("saved");
});

第三部分 行列的操作

看代码看注释

var Excel = require("exceljs");

var workbook = new Excel.Workbook();

// 标签创建
var worksheet = workbook.addWorksheet("第一个标签");
// 带颜色的
var worksheet2 = workbook.addWorksheet("第二个标签", {
    properties: {
        tabColor: {
            argb: "FFC0000"
        }
    }
});
// 设置列
worksheet.columns = [{
        header: 'Rating Period',
        key: 'id',
         38
    },
    {
        header: 'Name',
        key: 'name',
         32,
    },
    {
        header: 'D.O.B.',
        key: 'DOB',
         10,
        style: {
            numFmt: 'dd/mm/yyyy'
        }
    }
];

/// 根据ID添加值
worksheet.addRow({
    id: 1,
    name: 'John Doe',
    dob: new Date(1970, 1, 1)
});
worksheet.addRow({
    id: 2,
    name: 'Jane Doe',
    dob: new Date(1965, 1, 7)
});

worksheet.getCell(1).value = "Z";


// 直接赋值
worksheet.getCell('A6').value = "1989";

// 合并单元格
worksheet.mergeCells('A4:A7');
// 合并四个格子
worksheet.mergeCells('A10', 'B11');

// ===== 格式化显示，
// 数字 1.6 显示 '1 3/5'
worksheet.getCell('A1').value = 1.6;
worksheet.getCell('A1').numFmt = '# ?/?';
// 显示 1.60%
worksheet.getCell('B1').value = 0.016;
worksheet.getCell('B1').numFmt = '0.00%';
// ===== 字体显示
worksheet.getCell('A3').font = {
    // 字体名
    name: 'Comic Sans MS',
    // Font family for fallback. An integer value. 
    family: 4,
    // 字体大小
    size: 16,
    // 下划线
    underline: true,
    // 加粗
    bold: true,
};
worksheet.getCell('A3').value = "测试字体"

// ==== 对齐方式
worksheet.getCell('A1').alignment = {
    vertical: 'top',
    horizontal: 'left'
};
worksheet.getCell('B1').alignment = {
    vertical: 'middle',
    horizontal: 'center'
};
worksheet.getCell('C1').alignment = {
    vertical: 'bottom',
    horizontal: 'right'
};

// ===== 边框
worksheet.getCell('A1').border = {
    top: {
        style: 'double',
        color: {
            argb: 'FF00FF00'
        }
    },
    left: {
        style: 'double'
    },
    bottom: {
        style: 'thin'
    },
    right: {
        style: 'thin'
    }
};

// ==== 填充颜色
worksheet.getCell('A1').fill = {
    // 模式
    type: 'pattern',
    // 填充
    pattern: 'solid',
    // fgColor: {
    //     argb: 'FFFF0000'
    // },
    // 背景色
    bgColor: {
        argb: 'FF0000FF'
    }
};
// 图片相关操作直接看GitHub就好

// 直接创建一个Excel表
workbook.xlsx.writeFile("second.xlsx").then(function () {
    console.log("saved");
});
