There can be many ways to do this.One possible way is ..
First join the two tables using 'outerjoin'
It generates a new table with the columns of table2 appended to the colums of table1 with some NaN values for rows that don't match in the two tables. These NaN values can be replaced by empty values as below
for i=2:size(t,2)
for j=1:size(t,1)
if isnan(t{j,i})
