Question details

Full-width tables on a SharePoint page appear compressed or narrow upon entering edit mode, making the columns difficult to read without manual expansion.

How to Fix SharePoint Tables Becoming Narrow in Edit Mode

Product: Microsoft SharePoint
Device & OS: not provided
Scenario: A user tries to edit a published SharePoint page containing full-width tables and notices the layout drastically changes and shrinks.
Observed behavior: When the page enters edit mode, the table columns unexpectedly become narrow and squished together, whereas they display correctly in standard view mode.

Before you start

Verify that you have Full Control or Edit permissions for the SharePoint site, and try opening the page in an incognito window or an alternative web browser to rule out browser caching issues.

Document Layouts and Report to SharePoint Support

Because this layout shift is often tied to underlying SharePoint configuration updates or section constraints, gathering evidence and escalating to support is the recommended path.

SharePoint page editor layouts can sometimes conflict with table formatting, particularly if Microsoft has rolled out a recent update to modern page web parts. Testing the environment and providing detailed logs to your admin or Microsoft Support is the most effective way to resolve persistent rendering bugs.

Verify with other site editors

Ask colleagues who have edit access to the same SharePoint site to click the 'Edit' button on the page. Confirm whether they also experience the narrow table behavior to rule out local browser glitches.

Capture visual evidence

Take a screenshot of the table while the page is in standard view mode showing the correct full-width layout. Next, click 'Edit' in the top right corner and take another screenshot showing the compressed columns.

Inspect the section layout settings

While in edit mode, click the 'Edit section' button (the pencil icon) on the left side of the row containing your table. Ensure the section is set to 'One column'. If it is set to a restricted width, change it to 'One column' to see if the table expands.

Submit a support ticket

If the issue persists in a One-column layout, provide your screenshots and testing results to your IT administrator or navigate to the Microsoft 365 Admin Center to open a support ticket under the 'Support' > 'Help & support' menu.

Alternative Workaround: While waiting for a permanent fix, you can manually drag the column borders within the Text web part during edit mode to temporarily read and modify the table contents.

Frequently Asked Questions

Why do SharePoint tables look different in view and edit modes?

SharePoint's modern page editor injects additional user interface elements, such as web part toolbars and section margins, when you enter edit mode. These extra elements can constrain the available horizontal space, causing responsive tables to temporarily shrink or compress.

Can I prevent SharePoint tables from resizing automatically?

Tables created directly in the SharePoint Text web part are natively responsive. However, placing the table in a 'One column' section rather than a multi-column layout provides the maximum screen width, reducing the likelihood of aggressive column shrinking.

Does embedding an Excel file work better than using a SharePoint table?

Yes. If your table contains complex data or requires strict column widths, using the File Viewer web part to embed an Excel spreadsheet is often more reliable than using the native SharePoint text table editor, as it preserves the exact Excel formatting.
