How to add a sequential number in a column of tables cell?

Hey all, I have a 1 x 1280 cell which includes tables. In all tables, I want to add a number after the word that wrote in the first column. 1 for the first table, 2 for the second, 3 for third and so on.

For example:

In table one:

gridded_model

--------------------

GPCC_1

GPCC_1

GPCC_1

GPCC_1

..

GPCC_1

In table two:

gridded_model

--------------------

GPCC_2

GPCC_2

GPCC_2

GPCC_2

..

GPCC_2

In table three:

gridded_model

--------------------

GPCC_3

GPCC_3

GPCC_3

GPCC_3

..

GPCC_3

and so on untill the last table.

I don't want to change anything else in other columns and rows. As my cell is too large for attach here so I cut a little part of it and attached here.

Thank you all.

for i = 1:numel(Test)
    t = Test{i};
    t.gridded_model = strcat(t.gridded_model, '_', num2str(i));
    Test{i} = t;
end
