Feature request: Specify key column and variable columns separately

[cognifloyd]

Please let me set the variable start and end columns separately from the key_column.

There's a spreadsheet that I don't maintain or produce. I need to look up values in columns A-I from that spreadsheet based on column J (key_column=10). However, actions as they are assume that the key_column comes first, and variable columns follow. So, with the current implementation I can only look up values in columns K+.

Currently the code sets _variable_start_column to key_column + 1 and then looks for the next cell in the header row that is blank, and sets _variable_end_column to one less than that blank column.

It shouldn't be too much work to add two more parameters variable_start_column and variable_end_column, and use those if they are set instead of the current logic.

This change request seems reasonable to me.

You can also get your hands dirty and look into contributing that change yourself :)
