Bug in Dataset Alignment option for Center (still in version 14.2)

Rodrigo Murta, Looqbox
Posted 3 years ago

I'm using version 12.3. The Dataset Alignment is not working for the Center option, neither for the entire Dataset nor for a specific column.

Dataset[{
      <|"colA" -> 1, "colB" -> 2, "colC" -> 3|>
    , <|"colA" -> 4, 
"colB" -> 5, "colC" -> 6 |>
    }, Alignment -> Center
]

case 1

Dataset[{
      <|"colA"-> 1, "colB"-> 2, "colC"-> 3|>
    , <|"colA"-> 4, "colB"-> 5, "colC"-> 6 |>
    }, Alignment->{"colA"-> Right, "colB"-> Center, "colC"-> Center}
]

Try this:

Dataset[
  {<|"colA"->1,"colB"->2,"colC"->3|>,<|"colA"->4,"colB"->5,"colC"->6|>},
  Alignment->{"colA"->Right,"colB"->{Center,Automatic},"colC"->{Center,Automatic}}
]

Unfortunately, it still doesn’t work, even on version 14.2. When I use {Center, Center}, it does center, but the vertical spacing between lines changes, disrupting the layout of the dataset.

Well, I'm not entirely sure why, but Dataset seems to need both vertical and horizontal alignments to be specified. In the documentation, the default Alignment for Dataset is {Left,Baseline}. Maybe when you just set Alignment->Center all it does is replace Baseline with Center. I don't know. But anyway, if you use a pair for Alignment, the Dataset displays as expected. For example, try Alignment->{Center,Center}.
