How to set cell width when export .xlsx files with js-xlsx

Question

I am trying to set a fixed column/cell width to my exported excel files with js-xlsx.

EDIT:

Here is the source of js-xlsx: https://github.com/SheetJS/js-xlsx

Similar to cell width, you can set the cell height in the following way

var wsrows =  [
                 {hpt: 12}, // row 1 sets to the height of 12 in points
                 {hpx: 16}, // row 2 sets to the height of 16 in pixels
               ];

ws['!rows'] = wsrows; // ws - worksheet

Hint: If your worksheet data is auto generated and you don't know how many rows and columns are get populated then you could use the following way to find the number of rows and columns in the worksheet for doing cell width/height formatting.

var range = XLSX.utils.decode_range(ws['!ref']);
var noRows = range.e.r; // No.of rows
var noCols = range.e.c; // No. of cols
