How can I adjust column width in Invoice List by Date?

Welcome to Community, @communityoil.

I have some information about adjusting the header portion of the invoice list report. You can adjust your headers alignment by clicking the Customize button. Let's go to your report to see it.

1. Go to Reports, then type Invoice List.
2. Click the Customize button at the top right of your screen.
3. Scroll down towards the Alignment section. Then, change the Header drop-down.
4. Hit Run report.

Learn more about customizing reports at this link: Customise reports in QuickBooks Online.

If you need help with other tasks in QBO, you can browse for specific topics here and look for responses that fit your concern.

Feel free to reply to me anytime if you still have questions or concerns with reports. I'll be around for you. Take care and have a wonderful weekend ahead.
