By default, all columns are selected and will be imported.
Specific columns may be selected (or unselected) using the
standard Microsoft Windows method of either
Mouse click to
toggle the selection of individual columns, or
Mouse click to select
a range of columns.
The background color of a column shows the status of each column. The color white means that the column has been selected, and therefore it will be imported. Conversely, a gray background means that the column will not be imported.
Right-clicking anywhere in the preview grid opens a context-menu
with either a
Select None or
All option, depending on the current status.
