- Bulk column deletion by (column name) range. Without this feature, we are

issue, please raise your voice, as the feature has been tabled due to lack
of interest.
I think the lack of interest here has been this: it's unusual to want
to delete columns for which you do not know the names, but also not
want to delete the entire row. Is there any chance you're trying to
delete the entire row, or is it truly the case I just described?

Our use case is time-series data (such as sampled sensor data). Each
row describes a particular statistic over time, the column name is a
time, and the column value is the sample. So it makes perfect sense to
want to delete columns for a given time range. I'm sure there must be
numerous other use cases for which using a range of column names makes
sense.
