Ias ume that you are referring to a non-continuously selected range of columns, ie. column B and E, or column B, then D, then E. If I select column range B:D I can delete them , and I suspect so can you.

This would then be a question of deletion of an non-coninuous selection. This is bug #19827

No this is an incorrect assumption. A csv file was opened using gnumeric. Columns a,b,c were selected to be deleted, to allow only a single column d of data. This action could not be performed; column a had to be selected, then deleted, before column b, etc.

This is not the same deletion

@inpost, I can not replicate your problem based on the info given. 

Please explain in detail:

1) How are you selecting columns A,B,C ?
2) How are you trying to delete those columns (ie. sheet context menu, or Edit->Delete->Columns, or ?) ?


What I am doing is:

Click on the header of column A and drag to column C. Now columns A to C are selected. Right-click on the selection and choose "Delete 3 Columns" from the context menu.

Used 'ctrl' and mouse to select each column, after multiple columns selected (shown by change in colour) pressed 'delete', then received error that multiple selection not possible.

Yes, using ctrl creates a discontinuous (multiple) selection even if the parts of the selection happens to be adjacent. This is part of bug #19827.

Of course a simple workaround is to select the columns A,B,C as a single selection as described at the end of comment #3.
