To do this you will need to create a filter you can define filter like this
filters:{ sizeInMb(value){ let sizes = ['Bytes', 'KB', 'MB', 'GB', 'TB']; if (value == 0) return '0 Byte'; let i = parseInt(Math.floor(Math.log(value) / Math.log(1024))); return Math.round(value / Math.pow(1024, i), 2) + ' ' + sizes[i]; } },
That's it now call this filter where you want to display size in mb,kb etc.
<td>{file.file_size | sizeInMb}</td>
Hope it helps
