Change display unit in matrix

For a matrix, how to change the display unit, from $ to 1k$, or 1M$..

On approach I can think of is to create a measure or column for each column of data, then do something like display_value000 = value000/scale...  and scale is updated by the choice of either $, 1k$ or 1M$? 

Any easier solutions? such as to format the matrix itself? 

Thank you
