Can I create sortable or filterable tables in Squarespace?
The Custom Table Block itself does not document built-in column sorting or filtering. To make a Squarespace table searchable, you pair the Custom Table Block with the Universal Filter plugin, which adds live search and filtering to Table Blocks alongside blogs, products, and galleries. Native sort-by-column behavior is not confirmed in the product documentation, so confirm on the product page before relying on it.
What the Custom Table Block does natively
The plugin renders HTML5 tables from Google Sheets, CSV, or manual data and supports unlimited rows and columns, but its documentation does not describe built-in sorting or filtering controls (Squarewebsites).
Making tables searchable with Universal Filter
To add search and filtering to a table, pair the Custom Table Block with the Universal Filter plugin. Universal Filter explicitly supports Table Blocks among its filterable content types, so visitors can search and narrow table rows in place on the page (Squarewebsites).
Universal Filter is a separate one-time purchase ($89) licensed per website, and the two plugins are designed to work together for searchable tables (Squarewebsites).
