How can I expand the row of Zoho?

Dear Sir,

We are writing to know that why we can't add a row or inset a new row in Zoho.In recent days,when we want to add a new row of our files,it prompted that the row is reaching limited rows and we can not add one.

For the convenience to solve the probelms,we will attach a pricture for your reference but in Chinese.Hope you can understand that.



So we want to know why these happens and how this can be solved?

Looking forward to your reply.

Thank you so much for your time.
