Hi, I have 2 tables example:
TA=
'Name' 'Code'
'AFG' 120
'CAN' 210
'BER' 121
'FIJ' 910
'KOS' 991
'HAW' 101
'CHN' 211
TB=
'Name' 'Value'
'AFG' 0.5
'CAN' 1.2
'BER' 2.1
'FIJ' 9.1
'CHN' 0.2
'HAW' 1.6
I need a table TC in order of TA but containg the corresponding value from TB
'Name' 'Code' 'Value'
'AFG' 120 0.5
'CAN' 210 1.2
'BER' 121 2.1
'FIJ' 910 9.1
'KOS' 991 NaN
'HAW' 101 1.6
'CHN' 211 0.2
I know I need to use the ismember function for this, but not sure how to implement it here

>> TC = outerjoin(TA,TB,'MergeKeys',true)
TC =
Name Code Value

>> [TC,idx] = outerjoin(TA,TB,'MergeKeys',true);
