ShinobiDataGrid and column re-ordering



I have the following problem.  I’m using Shinobegrid and add as per the API columns. The number of column will grow as per user interaction.

However, I always need a column at the end that will display a result based on all the other column value.

I have not found a way to do this.  I can get the existing column via the call columns.  but I cannot update it as it is a NSArray type.

The only way so far that I’ve found is to completely rebuild the grid every time I add a column.  Is there a better way?



Well, in the end, it was easier to delete the last column, add the one that I want then add the last column again.

Less trouble but it would be nice to have a way to do this.
