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
but the question isn't clear enough to know.

I think the missing part is an if isempty test, which the user seems reluctant to code.
