This cell renders the source name of a row. For example, if the row was generated from a folder source with the path name
path/test, the cell will render
path/test with a folder icon. If a row was generated from loom file data, Internal will be rendered instead.
This cell is uneditable.
A column with a source cell type will be added when the first source is created. If you would like to hide this column, you may toggle its visibility.
