# Filling in Input tables with a schema

To fill in the input tables, you need to define either the schemas of the input components connected to the tMap component on your design workspace, or the input schemas within the Map Editor.

For more information about setting a component schema, see [Defining component properties](https://help.qlik.com/talend/en-US/studio-user-guide/8.0/defining-component-properties).

For more information about setting an input schema in the Map Editor, see [Setting schemas in the Map Editor](https://help.qlik.com/talend/en-US/studio-user-guide/8.0/setting-schemas-in-map-editor).
