Every column in the entries table was sized to its button text with nothing
spare, so with flex-wrap on the action cell the Edit and Delete buttons
wrapped out of their 128px column and sat on top of the entry description.
The order column was tighter still, and its Up/Down buttons carried almost
no padding, which made them hard to hit as well as hard to read.
Widened the order, type and action columns to fit their contents on one
line, stopped the action cell wrapping, gave the buttons real padding, and
added vertical cell padding with top alignment so a two-line entry no
longer runs into the row beneath it.
