Aligning matrix columns

jm's picture

Can anybody tell me how to left-align matrix columns in SWP 6.0.10?

When I click on Insert/Math Objects/Matrix (or on the matrix icon in the toolbar) and choose the number of rows and columns, each cell in a column is centered within the column. Selecting a column, or the whole matrix, and right-clicking offers several matrix options but not one to align each cell in a column to the left.

It is also curious that selecting just one column of the matrix and right-clicking brings up a menu with Properties on it but clicking on that does not actually bring up any options.

I am using Mac OS X 10.11.2 (El Capitan).
