UX for Tables with Too Many Columns: 7 Fixes That Work
By Justin Campbell, Lead Product Designer
How do you design a table with too many columns? Start by ranking columns by how often people need them for the main task. Show the top ones by default, then handle the rest with column choosers, frozen key columns, expandable rows or a detail view. Horizontal scrolling is a last resort, not the plan.
1. Rank every column by the main task
List each column and ask: does someone need this to do the table's main job? You will usually find a handful are essential, a few are useful sometimes, and many are only needed in a detail view. Show the essentials by default.
2. Let people choose their columns
A column chooser lets each person show and hide columns, often with a saved view. It works well in tools used by different roles: finance wants different columns than operations.
3. Freeze the identifying column
If sideways scrolling can't be avoided, freeze the first column (the name or ID) so people never lose which row they are reading. Pair it with a frozen header row.
4. Combine related columns
Two columns that are always read together, like city and state or first and last name, can often share one cell, with a secondary line for the second value.
5. Move detail into an expandable row
Columns that matter only after someone picks a row belong in an expandable row or a side panel, not across the top.
6. Tighten the density
Smaller padding and a compact row height fit more on screen. Offer it as an option, because not every user wants compact.
7. Question whether it's one table
Sometimes 25 columns are two tables pretending to be one: a summary and a detail. Splitting them is often the cleanest fix.
Test the fix on real data
Column widths that look fine with "Lorem ipsum" break with real names and long product codes. Always check the layout with realistic values. In the GridForge table builder, Intelligent Fill completes a column from one typed value, so you can test widths with realistic content quickly.

Not always, but it makes comparison harder. If you need it, freeze the first column so the row stays identifiable.
