How to sort all rows in one table based on one row from the table and another table
Show older comments
I have two different tables one with names (table 1) and others with names and data (table 2) but the second table is out of order. I want to order the names in table 2 by the order in table 1 but also not lose the data in the row. For example:
Table 1: Table 2:
Mom Sister 25 67 89
Dad Mom 88 76 23
Sister Dad 90 45 28
and I want to sort it according to table 1 so
Sister 25 67 89
Mom 88 76 23
Dad 90 45 28

t1 = table({'Mom';'Dad';'Sister'},'VariableNames',{'Names'})
t2 = table({'Sister';'Mom';'Dad'},[25;88;90],[67;76;45],[89;23;28],'VariableNames',{'Names','Var1','Var2','Var3'})
t3 = join(t1,t2) % the simple MATLAB approach

Read about ismember
T1 = {'Mom', 'Dad' 'Sister'} ;
T2 = {'Sister', 'Mom', 'Dad'};
[c,ia] = ismember(T1,T2) ;
T2(ia)
Now use the indices ia to reorder your table. For a table T, you can use
T = T(ia,:)
