    })
    .then(response => {
            let structArray = []
            for (let [index, value] of response.data.entries()) {
                structArray.push({
                    SalesOrderNumber: value.so_id,
                    SalesOrderDate: (value.so_date.trim().length ? moment(value.so_date, 'MMMM, DD YYYY HH:mm:ss', true).format('MM/DD/YYYY'): ''),
                    ShipmentStatus: value.shipment_status,
                    Remarks: value.remarks,
                    ID: value.id,

            ws.columns = [

            ]
            let wb = XLSX.utils.book_new()
            wb.Props = {
                Title: "Production Schedule Template",
                Author: "Admin"
            }
            XLSX.utils.book_append_sheet(wb, ws, "Schedule")
            let wbout = XLSX.write(wb, {type:"array", bookType:"xlsx"})
            saveAs(
                new Blob([wbout],
                {type:"application/octet-stream"}
            ), "production_schedule.xlsx")
        })
    .catch(error => {
        this.$store.commit('SET_ALERT',{type:'error', message:[error]})
        console.log(error)
    })
},

推荐答案

不幸的是，在SheetJS中没有轻松格式化列的功能.根据此问题，这是一种解决方法:

Unfortunately, there is no feature to format a column easily in SheetJS. As per this issue, here's a way to do this:

var colNum = XLSX.utils.decode_col("B"); //decode_col converts Excel col name to an integer for col #
var fmt = '$0.00'; // or '"$"#,##0.00_);[Red]\\("$"#,##0.00\\)' or any Excel number format

/* get worksheet range */
var range = XLSX.utils.decode_range(ws['!ref']);
for(var i = range.s.r + 1; i <= range.e.r; ++i) {
  /* find the data cell (range.s.r + 1 skips the header row of the worksheet) */
  var ref = XLSX.utils.encode_cell({r:i, c:colNum});
  /* if the particular row did not contain data for the column, the cell will not be generated */
  if(!ws[ref]) continue;
  /* `.t == "n"` for number cells */
  if(ws[ref].t != 'n') continue;
  /* assign the `.z` number format */
  ws[ref].z = fmt;
}
