How to remove default className?

[puhao7117441]

I try to use className to change table to my own style. But based on the documentation, className can only add a className. I do like below:
className: { td: 'people-table-td' }
Finally, the result is class="gridjs-td people-table-td". When there has conflict between people-table-td and gridjs-td I got issue.
How can I remove the gridjs default className?

Use 'style' to overwrite the dedicate css attribute can somehow solve this issue, but if the default className can be remove that will be much better.
