使用SheetJs导出Excel设置指定单元格格式

var tbl = document.getElementById('sheetjs');
var wb = XLSX.utils.table_to_book(tbl);


var ws = wb.Sheets["Sheet1"]; //  get the current sheet
console.log(ws["A2"].v); //  default v value '4.56'

ws["A2"].z = "$0.00"; //  format the cell

delete ws["A2"].w; // delete old formatted text if it exists
XLSX.utils.format_cell(ws["A2"]); // refresh cell

console.log(ws["A2"].w); // new formatted cell '$4.56'
