Is there any maximum for the size of matlab table?

table() objects are restricted to:
2000 rows and 5000 columns is no problem at all. Here is one 50 times bigger (100 times bigger ran out of memory on the system I was executing on)
t = array2table(randi(9, 10000, 50000, 'uint8'));

It depends on what you want to store into this table. You can have a look here to find more informations:

There are theoretical limits (based on limitations of the operating system's ability to address memory) that you are highly unlikely to reach especially now that MATLAB is a 64-bit application.
There are also practical limits (based on how much memory is available on your system) that you likely won't reach.
2000 rows and 500 variables should be well within the practical limit unless you have a lot of other data in your workspace. You can check before filling in the data:
T = table('size', [2000 500], 'VariableTypes', repmat("double", 1, 500));
