Behavior

A table chart resolves a cell’s null text in this order. This order applies to table chart cells only.
  1. The column’s Null display setting
  2. The dimension‘s null_display value.
  3. The table’s Null display setting.
  4. The default ∅ symbol.
To show a blank cell for a dimension with null_display set, set the column’s Null display setting, or set null_display to an empty string (""). An empty string is a valid value for null_display and displays as a blank cell. This is different from leaving null_display unset, in which case the table’s setting is used instead. KPI and Markdown visualizations show the dimension‘s null_display value directly. They don’t have a per-tile null override.
Table charts, KPIs, and Markdown tiles use null_display. Vega charts, the Results grid, pivot headers, the formula bar, and downloads always show ∅ for null values.
