#### Tab Settings
Since settings are for an individual tab, admins must make changes to each tab if they want changes to apply to that tab.
To modify the settings for an active tab, admins can select 
* **Edit cells —** Allows users to make changes to existing values in the DataSet.
* **Add rows —** Allows users to create new rows.
* **Delete rows —** Allows users to mark rows for deletion the next time changes are written to the DataSet.
* **Bulk edit —** Allows users to view the **Bulk Edit** button and modify the values of all the cells under a selected column.
##### Columns
The **Columns** settings allow admins to control the column configurations and which columns are editable from the app.
The modal displays a list of each column in the DataSet. except key columns (upsert DataSets). The only edit you can make to key columns is the column name, from the main screen of the app.
If the DataSet/tab already has changes in any field, admins cannot change the column configuration—all changes must first be discarded.
In the modal, each displayed column has the following controls beside the column name:
* 
The last area in the **Columns** settings is **Column label**. In this area, you can edit the column name that displays in the table. For some columns, you can also define an **Input type** —how users interact with the fields in that columns. Possible options include **Manual input** and **Option list**.
##### Filters
The **Filters** settings allow admins to define the way Page Filters and In-App Filters are used to filter the data displayed in the DataSet/table.
* **Use Page Filters —** When this box is checked, Filters defined in the dashboard where the app card displays are transferred to and used by the app.
* **Disable In-App Filters —** When this box is checked, In-App Filters are removed, and only Page Filters defined in the dashboard where the app card displays are used by the app. Checking the box also removes the **Filter** option from the app toolbar.
* **Conflicting** **Filters —** When a column has both a Page Filter and an In-App Filter, only one can be used. This setting allows admins to control which Filter type is used when there is a conflict.
#####
#### Date Format
The **Date Format** setting allows admins to control the way that date fields display on the table view.
Possible options include:
* **Default —** Date displays in this format: Jan 6, 2023
* **Date shorthand —** Date displays as MM/DD/YYYY
* **Full date —** Date displays in this format: January 6, 2023
* **YYYY-MM-DD —** Date displays in the given format.
* **Custom —** Admin can define a custom format from options available in the modal.
