To access the *Data Explorer*, in [Workbench](/content/admin/workbench),
click the **Data** tab of the left-hand navigation pane.
## General Features
At the top of the *Data Explorer* tab are actions not tied to a specific object
type:
* Search box - filters displayed objects across all three domains, by keyword
* Refresh icon - refreshes the list of displayed objects
* **+** icon - adds a new data object
- set
[column-level security](/content/admin/workbench/ui/explorer/data#wb-explorer-data-tv-config-cls) on
this column for users/roles
* 
- remove this column from the table
Column-Level Security
When the *Column Permissions* is clicked for a column on the
table create/edit *Column Definitions* page, the
**Column Permissions** pop-up will appear.
Click the name of a user or role on the left pane to show the corresponding
*column-level permissions* that user/role has on this table in the right pane,
and configure them:
* **Enabled** - toggle whether *column-level permissions* on this
table's column are active for the selected user/role; this will grant the
selected user access to this column's data
* **Filter** - enter the filter expression that should be used to
define the records in this column the selected user **can** access;
effectively adding *row-level security* to this column
* **Transform Type** - optionally, character-based column values
can have one of two transform functions applied in order to conceal the true
values from the user/role to whom the access is granted:
* **Obfuscate** - conceal text values by converting them to
"random" whole numbers, where all occurrences of a given text value will
convert to the same number
* **Mask** - conceal text values by replacing one or more
sequential characters in the text value with a single "masking" character:
* **Start Position** - the 1-based position of the first
character to mask
* **# of Masked Characters** - the number of characters after
(and including) the first one to replace with the masking character
* **Mask Character** - the character used to replace column
value characters
Click **OK** once all *column-level security* modifications have
been made.
See [Column-Level Security](/content/security/sec_concepts#sec-concepts-perm-table-col) for details.
