Adding new columns in a Table?

Question

0 个投票

I think this should be quite simple, but somehow I couldn't find the solution online.

I have two Tables, eg: Table1 and Table2. How to add let say two columns from Table 2 to Table 1.

I have tried this, but it does not work as the two input must be in a table form.

T1 = [T1 T2.ColumnA T2.ColumnB]

The problem with this is that you're trying to concatenate a table with two doubles (I'm guessing). As Walter shows, you need to concatenate tables.

Hi Peter. Yes, you are right, the columns are doubles. Walter's answer works :)

T1 = [T1, T2(:,{'ColumnA', 'ColumnB'})]

Note: this is only permitted if T1 does not already have variables with the same name.

Sorry for my late response to your answer. The code works brilliantly. Thank you.
