Add a column to a table
You can add columns when you create a new custom table, or you can add columns to an existing table at any time. Adding a new column is the same whether you are creating a new table or adding to an existing table.
1.Sign in to Power Apps.
2.Select the Data option on the left-hand menu.
3.Open an existing table or create a new table.
4.Select Add column on the menu at the top of the page.
5.Enter information in the following columns:
a. Display name - The name that is shown to users.
b. Name - This is the internal name that is used by your application.
c. Data type - This is the type of data that you want to store in the column.
d. Required - Select this check box if you want to ensure that this column always has a value when a user tries to add a record to this table.
e. Searchable - Clear this check box for columns for the table that you do not use. When a column is searchable, it appears in Advanced Find and is available when you are customizing views. Clearing this check box reduces the number of options that are shown to people who are using Advanced Find, and helps make it easier for users to create custom views without seeing unused columns. Clear the Searchable check box when you are working with columns in a standard or complex table that you do not use.
f. Calculated or Rollup - Use to define a calculation or a rollup in this column.
g. Description - This is a description of the column.
