That's this code here: https://github.com/simonw/datasette/blob/7af67b54b7d9bca43e948510fc62f6db2b748fa8/datasette/views/table.py#L631-L645","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",1318907685,500 error if sorted by a column not in the ?_col= list,

Possible fixes:

- Always include the sort column in the list of columns that are selected, then filter that out before they are displayed
- Use a second query to figure out the `_sort` or `_sort_desc` value for that last row, since we know its primary key (we always select primary keys)

Not sure which solution is more elegant. I think it might be the second one.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",1318907685,500 error if sorted by a column not in the ?_col= list,
