/ * * 
 * generating XLSX 
 * @param generate a file path P 
 * @param cols column names 
 * @param data line, a two-dimensional array 
 * / 
function genXlsx (P, cols, Data) { 
    nodeXlsx the let = the require ( './ Node-XLSX-C' ); 
    the let D = [{ 
        name: "Sheet1" , 
        Data: [ 
            cols, 
            ... Data 
        ] 
    }]; 
    // cols specify the width of the column! 
    FS. writeFileSync (P, nodeXlsx.build (D, {
         'cols!': [{WCH: 60}, {WCH: 20 is }] 
    }), { 'In Flag': 'W' });
}
// Specify cell contents style: four directions black frame 
the let contentCellStyle = { 
    border: {

    },
    alignment: {
        horizontal: "center"
    }
}

genXlsx("1.xlsx", [{
    v: "表头1",
    s: headerStyle
}, {
    v: "表头2",
    s: headerStyle
}], [[{
    v: 123,
    s: contentCellStyle
}, {
    v: 456,
    s: contentCellStyle
