使用 js-xlsx 样式化 xlsx 文件

Question

我到处寻找解决方案。在 javascript 中编写新的 xlsx 文件时，如何向单元格添加样式？ 当我的意思是样式时，我想在第一行（A1）中添加背景颜色，并且还希望所有工作表都是 RTL 而不是 LTR 我在文档中进行了搜索，但未能成功实施此选项 如果有人能提出解决这个问题的方法，我将不胜感激

这是我的脚本：

    function getCsvFile(value) {
        const currentDate = getCurrentDate()
        let obj = []
        let currentCompany = ''
        value.split('\n').forEach(row => {
            let i = 0;
            if (!row.startsWith('[') && !row.startsWith(']')) {
                if (!hasNumber(row.split(' ')[0])) {
                    currentCompany = row
                    const isExists = obj.find(company => company.name === currentCompany)
                    if (isExists) {
                    } else {
                        obj.push({ name: currentCompany, products: [] })
                    }
                } else {
                    obj = obj.map(company => company.name === currentCompany ? { ...company, products: [...company.products, row] } : company)
                }
            }
        });

        const maxRows = Math.max.apply(Math, obj.map(function (o) { return o.products.length; }))
        const headers = obj.map(({ name }) => name)
        let rows = []
        for (let i = 0; i < maxRows; i++) {
            let row = []
            obj.forEach(element => {
                row.push(element.products[i] || '')
            });
            rows.push(row)
        }

        var wb = XLSX.utils.book_new();
        wb.Props = {
            Title: "SheetJS Tutorial",
            Subject: "Test",
            Author: "Red Stapler",
            CreatedDate: new Date(2017, 12, 19)
        };

        wb.SheetNames.push(currentDate);

        var ws_data = [
            headers,
            ...rows
        ];
        var ws = XLSX.utils.aoa_to_sheet(ws_data);
        ws['A1'].s = {
            fill: {
                patternType: "none", // none / solid
                fgColor: { rgb: "FF000000" },
                bgColor: { rgb: "FFFFFFFF" }
            },
            font: {
                name: 'Times New Roman',
                sz: 16,
                color: { rgb: "#FF000000" },
                bold: true,
                italic: false,
                underline: false
            },
            border: {
                top: { style: "thin", color: { auto: 1 } },
                right: { style: "thin", color: { auto: 1 } },
                bottom: { style: "thin", color: { auto: 1 } },
                left: { style: "thin", color: { auto: 1 } }
            }
        };
        var wscols = headers.map(column => {
            return { wch: column.length + 20 }
        });

        ws['!cols'] = wscols;
        wb.Sheets[currentDate] = ws;
        var wbout = XLSX.write(wb, { bookType: 'xlsx', type: 'binary', });
        function s2ab(s) {

            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;

        }
        saveAs(new Blob([s2ab(wbout)], { type: "application/octet-stream" }), 'test.xlsx');
    }

非常感谢！

这是节点版本 XLSX 库 [0.16.0][1] 中工作簿的结构：

index.d.ts：

export interface WorkBook {
    /**
     * A dictionary of the worksheets in the workbook.
     * Use SheetNames to reference these.
     */
    Sheets: { [sheet: string]: WorkSheet };

    /** Ordered list of the sheet names in the workbook */
    SheetNames: string[];

    /** Standard workbook Properties */
    Props?: FullProperties;

    /** Custom workbook Properties */
    Custprops?: object;

    Workbook?: WBProps;

    vbaraw?: any;
}

export interface WBProps {
    /** Sheet Properties */
    Sheets?: SheetProps[];

    /** Defined Names */
    Names?: DefinedName[];

    /** Workbook Views */
    Views?: WBView[];

    /** Other Workbook Properties */
    WBProps?: WorkbookProperties;
}

/** Workbook View */
export interface WBView {
    /** Right-to-left mode */
    RTL?: boolean;
}

此代码的基础我可以像这样更改对齐方式并将输出文件对齐方式更改为正确：

if (wb.Workbook) {
   wb.Workbook.Views[0]['RTL'] = true;
} else {
    wb.Workbook = {};
      wb.Workbook['Views'] = [{RTL: true}];
}
