set columns type

in my project, I want to set all rows type as header, every row’s type can automatically seted as header’s type. I found type is supported in this lib, then I try somethings like this:

worksheet.columns = [
    { header: 'Id', type: Excel.ValueType.Number },
    { header: 'Name', type: Excel.ValueType.String  }
];

but it didn’t work. Is there a way to set the type of rows?

i think we can use numFmt=“” in the columns… it will set it type for text it should be ‘@’
