I produce a table in for loop that in some cases all elemtents of table might be empty. For example table.A= 0×1 empty double column vector.

How can I convert each element of empty table to zeoro?

So, you have one table with 0 rows and 9 columns. Obviously, it's difficult to fill 0 rows with anything. The table could be expanded to a given number of rows, is that what you want to do? Why?

@Guillaume:

This table is being produced in a loop and I wanted to have zero table when I dont have any data because this table is being used later for other calculations but I changed my strategy and it is solved for now.

Thanks Guillaume for your help.

The answer might be

>> t = table.empty(0,3)
t =
  0×3 empty table
>> t{1,:} = 0
t =
  1×3 table
    Var1    Var2    Var3
    ____    ____    ____
     0       0       0
