The Clear Custom Format button is used to undo custom formatting and revert to the default formatting format as defined by the current theme.
Component Ribbon
To undo all contextual formatting, regardless of whether it was applied to a row, column, or data cells, click the Clear Custom Format button (red highlight below) from the Component ribbon. Alternatively, select a contextually formatted row or column and click the Clear Custom Format button while the selection is still active; this will clear the custom formatting only for the given row or column.
Formatting Panel: Clear Custom Formatting
Custom formatting can be cleared from columns, rows, or data cells using the Formatting Panel. This enables users to undo contextual formatting for only a specific cell type, rather than the entire grid.
