How to change variable names to headings in table?

I have the following table in my code:

table = table(ht,hGt,Tkt,Prt,Drt);

When the table is displayed I want each variable to be named under the following headings:

ht = "Geometric Altitude (km)"
hGt = "Geopotential Altitude (km)"
Tkt = "Temperature (K)"
Prt = "Pressure Ratio"
Drt = "Density Ratio"

What command can I use that allows me to use these heading, I haven't found one that allows me to use an invalid variable name.

Thanks, Jake

Use table's optional argument VariableNames:

names = {'GeometricAltitude_km', 'GeopotentialAltitude_km', 'Temperature_K', 'PressureRatio', 'DensityRatio};
table = table(ht,hGt,Tkt,Prt,Drt, 'VariableNames',names);

Edited to remove spaces from the cell array strings.

I've tried this before but when I run the code I get the following errors:

Error using matlab.internal.tableUtils.makeValidName (line 33) 'Pressure Ratio' is not a valid variable name.

Error in setVarNames (line 48) [newnames,wasMadeValid] = matlab.internal.tableUtils.makeValidName(newnames,exceptionMode); % will warn if mods are made

Error in table (line 304) t = setVarNames(t,vnames); % error if invalid, duplicate, or empty

Error in AerE161_FinalProject (line 156) table = table(ht,hGt,Tkt,Prt,Drt, 'VariableNames',names);

Sorry, that was my oversight. I have edited the strings to remove all space characters. All variable names have to follow these rules:
