The Missing Data Component will allow you hide data cells in the Timing Tower.
Components are imported directly from within iRacing Live Timing. In iRacing Live Timing press F4 to open the Remote Control Tab and then F2 to enter Edit Mode. Click the Import Library button and select from the list the component you want to import. The component will then be imported to your Remote Control Tab in the first available empty space (often below existing components).

This Component consists of a row of Show buttons and a row of Hide buttons. Each column relates to the matching column in the Timing Tower Component.
So if in the Timing Tower you have selected a column to display Pit time. By default each driver who has not completed a Pitstop will have an empty space in the Pit time cell against his name. Depending on the data it may display –/–/–.
By setting a column to Hide in this component it will display nothing against that driver, including the panel background.
Note that you should generally only use the Hide setting on the last column you are displaying in your Timing Tower otherwise the alignment will be incorrect when inner cells are hidden!
