How do I create a cell array inside a loop?

I have a Nx1 cell array of tables called 'T' and I am looking to extarct the variables in each table but the size of 'T' can vary as can the dimensions of the tables. My code is below.

I know this can be done in a for loop using something along the lines of - for i = 1:length(data)... but how do I write the part that can create a new vars number array to hold the VariableNames in?

vars1 = T{1}.Properties.VariableNames;
vars2 = T{2}.Properties.VariableNames;
vars3 = T{3}.Properties.VariableNames;
...
...
...
varsX = T{N}.Properties.VariableNames;

Understood!

@Cathal: just use a cell array:

F = @(t) t.Properties.VariableNames;
V = cellfun(F, T, 'uni',0)

Thanks Stephen. That will work for what I need
