Retool Table Column Header Text Wrapping: How to Fix It

OTC Team··4 min read

If you've spent time building data tables in Retool, you've almost certainly hit this wall: your column header text either gets clipped mid-word or forces you to stretch the column to an awkward width just to make it readable. Retool table column header text wrapping isn't natively toggleable yet — it's a long-standing community feature request — but there are several solid workarounds you can ship today. This guide walks through all of them.

Why Retool Column Headers Clip or Overflow

By default, Retool's Table component renders column headers in a single line. When the header label is longer than the column's rendered width, one of two things happens: the text gets truncated with an ellipsis, or the column expands to accommodate the full string — breaking your carefully designed layout. There's no built-in CSS toggle exposed in the UI to force headers to wrap onto multiple lines, which is why this has been a recurring ask in the Retool community since at least 2021.

Workaround 1: Shorten the Column Header Label

The fastest fix is also the most obvious — rename your column headers to be more concise. If your header reads Total Invoiced Amount (USD), consider trimming it to Invoiced (USD) or just Amount if context makes the meaning clear. In the Table component's column settings, click the column you want to edit and update the Header field directly. This takes about 30 seconds per column and requires no code.

The tradeoff is that overly abbreviated headers can confuse end users, especially if your table is consumer-facing or used by non-technical stakeholders. Use this approach when the meaning survives the trim.

Workaround 2: Use Abbreviations with a Tooltip

A cleaner UX pattern is to abbreviate the header label but surface the full name via a tooltip. Retool's Table column settings include a Tooltip field. Set your column header to the short form — e.g., Inv. Amt. — and paste the full label into the tooltip. Users who need clarification can hover, and your table stays compact.

  • Open the Table component in the editor
  • Click the column you want to update under Columns
  • Set a short string in the Header field
  • Paste the full descriptive label into the Tooltip field
  • Save and preview — hover over the header to confirm the tooltip appears

Workaround 3: Inject Custom CSS for Header Wrapping

If you need actual multi-line wrapping in column headers and you're on a Retool plan that supports Custom CSS, you can override the default header styles. Navigate to your app's Scripts and Styles section (the </> icon in the left sidebar) and add a CSS block targeting Retool's table header cells.

  • Open Scripts and Styles from the left sidebar
  • Click the Styles tab
  • Add the following CSS rule:

.retool-table th .th-content { white-space: normal !important; line-height: 1.3; }

This forces the white-space property from nowrap to normal, allowing header text to break across lines. You may also want to set a min-height on the header row so the layout doesn't shift awkwardly for columns with short labels. Note that Retool's internal class names can change between versions, so test this after any platform updates.

Workaround 4: Rename Headers Using a SQL or JS Transform

If your column names are coming straight from a database query and you don't want to manually rename each one in the UI, use a JavaScript transformer to rename keys before they hit the table. For example:

return query1.data.map(row => ({ "Inv. Amt.": row.total_invoiced_amount_usd, "Customer": row.customer_name }));

Wire this transformer as the Table component's data source instead of pointing directly at the raw query. This keeps your column names short and predictable without touching the database schema.

What to Do While Waiting for the Native Feature

The Retool team has acknowledged this request in their community forum. Until it ships as a first-class feature, the combination of abbreviated headers + tooltips covers the majority of use cases with zero custom code. If you have strict design requirements or are building a table that will be used by a large internal team, the custom CSS approach gives you full control.

  • For quick wins: rename and abbreviate headers in the column settings
  • For user-friendly tables: pair short headers with descriptive tooltips
  • For pixel-perfect layouts: use custom CSS to enable white-space: normal on th elements
  • For data-driven tables: use a JavaScript transformer to rename keys upstream

The Bottom Line

Retool table column header text wrapping is a gap in the platform's current UI — but it's a solvable one. The tooltip workaround is the most maintainable solution for most teams, while custom CSS is the right call if you need true multi-line rendering. Pick the approach that matches your constraints, and upvote the original feature request to help push it up the roadmap.
