By default, the column header of the grid shows the field type icon for each field. This also applies to the filter and sort buttons. To hide these icons, follow the steps below:
Go to the Styling & Customization section.
Turn off the Show field type icons toggle.
This setting will apply to all tables in a given portal where field-type icons are visible.
💡 Tip: The grid header, filters and sort options will all use the Title given to the field in the child form.
