# How to remove columns from a table in Cascade

It is often desirable to focus on specific data points while filtering out distracting details. Cascade offers the [Select Columns](/cascade/tools/transform/selectcolumns.md) tool to remove columns from the workflow without sacrificing the ability to access them later. The data is never deleted or removed from the source, maintaining the flexibility of retaining the information if necessary.

To utilize the [Select Columns](/cascade/tools/transform/selectcolumns.md) tool, drag and drop it onto the Canvas. Then, choose whether to keep or drop the selected columns.

If “[**Keep Selected Columns**](/cascade/tools/transform/selectcolumns.md#configuration)” is selected, only the chosen columns will continue downstream. If “[**Drop Selected Columns**](/cascade/tools/transform/selectcolumns.md#configuration)” is selected, the specified columns will be removed from the table, however, other columns, including new ones, will still flow downstream.

Lastly, select the columns you would like to keep or drop from the dropdown menu.
