Where T is your table:
idx = strcmpi(T.OutputCase,'Pushover-x');
out = T(idx,{'StepNum','GlobalFX','GlobalFZ'})
https://www.mathworks.com/help/matlab/matlab_prog/access-data-in-a-table.html
Note that if OutputCase really were the RowNames then you could have done this:
out = T('Pushover-x',{'StepNum','GlobalFX','GlobalFZ'})

"but it was error"
Then you need to tell us exactly what the error is. Show us all of the red text.
"so it cant take two filters in one variable ?"
MATLAB does not limit how many AND operators can be chained one after another.
But your logic using AND is most likely incorrect: can you show one single value of the OUTPUTCASE field whose value is both equal to "Pushover-X" and also to "MODAL" ? That is what AND means.
I am guessing that you intended to use OR:
idx = strcmp(T.Joint,'5') & (strcmp(T.OutputCase,'Pushover-x') | strcmp(T.OutputCase,'MODAL'));
or perhaps ISMEMBER or MATCHES or similar:
idx = strcmp(T.Joint,'5') & ismember(T.OutputCase,{'Pushover-x','MODAL'});
