can we add columns with name spaces while creating an eText format of the BI publisher report?

We have requirements to create and extract CSV files for another system as integration. The requirement was to have column names with space (e.g. First Name). We have done this in the SQL query using "First Name". In the result, the space got replaced with _ underscore. we tried to add the space in the eText, but the data didn't show up.

is there a way to accommodate this column spacing?
