How to store and use table variable name

I'm creating a function to grab data from a hefty Excel sheet. I want the function input to determine the data I grab. Ex, in this case prices is the column header (table variable name) for the data I care about.

grab_data('12345.xlsx','prices')

function data_out = grab_data(filename,data_to_grab)

data=readtable(filename);

for h = [1:height(data)]

data_out(end+1)=data.data_to_grab(h)

end

end

When I run something like this, I get an error that there is no table variable name 'data_to_grab'. It's reading the name of the variable literally. Please help!

data_out(end+1) = data.(data_to_grab)(h)
