Depends on which table and which Mathcad. Mixing units may not work.

I've never had mixed units work. I often define the input parameters into a matrix and then pull them out to assign units to them. When I do that I use column and row zero to hold important information in text format (e.g., if the instances of data are in the rows then in column zero I put the name of the point, and in row zero I put the name of the data item and the required units, it works for me). Then I can pull out each column or row vector and assign units to it.

"Belief" is the acceptance of an hypotheses in the absence of data.
"Prejudice" is having an opinion not supported by the preponderance of the data.
"Knowledge" is only found through the accumulation and analysis of data.

From my use of tables: Units must be stripped before adding to a table (IE Divide the number by the units you wanted reported such as Length/in or time/sec) or added post removal from table ((Data[1,4)*in)... i'm pretty sure it stores all information in a table as a matrix (not unit friendly).

You can store units in tables, provided they're all the same unit, i.e., a table of lengths or weights works tolerably well.

True, but it is amazing how seldom I find a table that all has the same units.

Also note, if you put units from a matrix input into an embedded excel it converts them to default units (Length to Meters or feet). I find it to be good practice to strip units before I pass to a table, excel, or graph.
