 ## Set table-level read access
 
-To create a [custom role](../../role-based-access-control/custom-roles.md) that lets specific users or groups read data from specific tables in a workspace:

-    
-    1. Navigate to your workspace and select **Access control (IAM)** > **Roles**.
-    
-    1. Right-click the **Reader** role and select **Clone**.

Azure custom roles apply to workspaces with either workspace-context or resource-context [access control modes](#access-control-mode) regardless of the user's [access mode](#access-mode).
 
 To define access to a particular table, create a [custom role](../../role-based-access-control/custom-roles.md):
 
 * Set the user permissions in the **Actions** section of the role definition. 
 * Use `Microsoft.OperationalInsights/workspaces/query/*` to grant access to all tables.
 * To exclude access to specific tables when you use a wildcard in **Actions**, list the tables excluded tables in the **NotActions** section of the role definition.

 For example, if a specific firewall is sending custom logs, create a resource group called *MyFireWallLogs*. Make sure that the API requests contain the resource ID of *MyFireWallLogs*.

-#### Considerations
+### Considerations
 
 - If a user is granted global read permission with the standard Reader or Contributor roles that include the _\*/read_ action, it will override the per-table access control and give them access to all log data.
 - If a user is granted per-table access but no other permissions, they can access log data from the API but not from the Azure portal. To provide access from the Azure portal, use Log Analytics Reader as its base role.
