Hi polachan,

VM12 jquery.dataTables.min.js:62 Uncaught TypeError: Cannot read property 'style' of undefined'

This error means that you are trying to get the style attribute of an undefined element.

Are you sure that you provided the right code? since there's no jquery datatable related code and literally no "style" in your provided code.

Anyway, the reason for this issue is most likely no value assigned to the corresponding object.

For example, in the js code you have: XXX.style but the XXX never be assigned a specific value or element.

Please check jquery.dataTables.min.js:62 and you might find  the true reason.

Best Regard,
