Below is my code to write these column data into an Excel spreadsheet using the writetable command:
T1 = table(Cruise, EXPOCODE, Station_no, Lon, Lat, Year, Month, Day, Time, Pressure, Depth, ...
Temperature, Temperature_flag_W, Salinity, Salinity_flag_W, CTDOXY, CTDOXY_flag_W, OXYGEN, OXYGEN_flag_W, ...
DIC, DIC_flag_W, TA, TA_flag_W, pH_insitu, pH_flag_W, pCO2_insitu, pCO2_flag_W, CO3_insitu, CO3_flag_W, ...
Silicate, Silicate_flag_W, Phosphate, Phosphate_flag_W, Nitrate, Nitrate_flag_W, ...
NitrateNitrite, NitrateNitrite_flag_W, Nitrite, Nitrite_flag_W, Ammonium, Ammonium_flag_W);
File_W = ['outputs/', app.File.Value, '.xlsx'];
writetable(T1, File_W)
The thing is that sometimes an entire column could be made up of NaNs or missing value indicators, -999. How do I write a program, so that it will only use the variables that have at least one real value into the final Excel file? If a column is composed of either NaN or -999 values, the entire column, as well as its corresponding flag column (made up of numerical number 5), should not appear in the generated Excel file.
Many thanks!

T_in_Excel = T1(:,any(~isnan(T1{:,:})));
writetable(T_in_Excel, File_W)

As a reminder, would you please help me with the flag column as well?
Many thanks!
