wxgrid - is there an easy way to set alignment of a column?

[tinnews at isbd.co.uk]

I'm using wxGrid and finding it fairly straightforward but I can't see
an easy way to set the alignment (left, centre, right) for a whole
column. 

There's SetDefaultCellAlignment() which sets the default for the whole
grid and there's SetCellAlignment() which sets it for a specific cell
but there seems to be no way to set the default alignment for a column.

Am I missing something or do I need to do it for individual cells as I
load the data?
