I read in a csv into a table and set each column's units with VariableUnits. I would like to be able to read the units for a certain column (say column 3, "Temp"). I would like to know if the temperature was recorded in degrees F or C or K.
I can use table{1,1}.Properties.VariableUnits to display the units for all the columns, but I can't figure out how to look up the units for just one column.
Also if I want to update the units for one column, how can I do that as well?

Jason -
T.Properties.VariableUnits{2}
will get you the units for the second column.
T.Properties.VariableUnits{2} = 'NewUnit';
will update the unit name for that column.

I figured out that calling the column at the end of the statement is the way to reference the column.
table{1,1}.Properties.VariableUnits{column_name}
Is the way to get the column information.
