+            The name gets the room the other columns leave, which in the dialog was next to nothing: it
+            may break anywhere, so a single character was enough for the browser. The minimum width
+            keeps it readable, and the type and the embedding wrap instead, so that the table still fits.
+            The minimum sits on a div, since browsers differ in whether they honor it on a table cell.
+            With "break-word" instead, a long name without spaces would push the table out of the dialog.
