Dear Jessica A,
Good day! Welcome to Microsoft Q&A forum!
Based on your description, I understand that you want to add another column and find how to extend table lines.
You can refer AI answer about resize table. I also attach the article about Resize a table by adding or removing rows and columns in Excel for your reference.
If you encounter difficulties while resizing the table, please inform me how you created it; if possible, you may also provide a screenshot of the problematic table. Since the AI cannot respond to you directly, please let me know if you experience any issues.
Your confirmation would be very helpful in ensuring you receive the most suitable support!
If you’re able to share a bit more about your situation, I might be able to suggest some helpful next steps.
Kindly let me know when there are updates or if you need further assistance. Any updates you’re able to share would be really helpful. I appreciate your time and look forward to hearing how things are going!
Thank you for your time and patience.
