I am having some trouble will developing my code to only save the table with different values to the file. So far I have,
savefile='Tumble Data User Applicable.mat';
PrevTable=load(savefile,'ATtablef');
ATcellf={AccelSN,Teststr,Accel0,Accel90,Accel180,Accel270,Temp0,Temp90,Temp180,Temp270,VB,HB,VSF};
ATtablef=cell2table(ATcellf);
ATtablef.Properties.VariableNames={'Accel S/N' 'Test date' 'Accel_0' 'Accel_90' 'Accel_180' 'Accel_270'...
'Temp_0' 'Temp_90' 'Temp_180' 'Temp_270','Vertical Bias','Horizontal Bias','Vertical Scalefactor'};
savepath='\\172.30.248.24\share\For Redmond\transfer\Alexandra\MatlabFiles';
savefile='Tumble Data User Applicable.mat';
save(fullfile(savepath,savefile),'ATtablef')
ATtablef=[PrevTable.ATtablef;cell2table(ATcellf,'VariableNames',ATtablef.Properties.VariableNames)];
savepath='\\172.30.248.24\share\For Redmond\transfer\Alexandra\MatlabFiles';
savefile='Tumble Data User Applicable.mat';
save(fullfile(savepath,savefile),'ATtablef')
If on a second run the table has the same values it should not be saved therefore, only values that are different in ATtablef may be saved to the file.
Any suggestions or resolutions?

The different values should be stored to the table and saved while, with the exact same values to previous runs should be disregarded and not saved.

That is not possible without changing the table format. You have numeric columns, and the only way to not save at those locations is to change the column from numeric to cell so that you could empty the cells at the places the numeric values are the same. Likewise for the datetime column. Your Accel S/N looks like it might perhaps be character, so that one would be okay since empty characters are okay in Excel.
