Find the maximum value of a column in a table

I have a spreadsheet that is read into a Matlab table. I need to get the maximum value in column 1. I thought the following would work, but it keeps throwing up an error.

MaxExpTime = max(A(:1));

The problem here is that A(:,1) returns a table not the values in the table. You can retrieve the values with A.(1) or A{:,1} but better practice is to use variable names (e.g. A.Var1) with a table:

A=table(rand(10,1))

A = 10×1 table
     Var1  
    _______

    0.92076
    0.69648
    0.27894
    0.40647
    0.90258
    0.21383
    0.17593
     0.8362
    0.23215
    0.95136

max(A.(1)) 

ans = 0.9514

max(A{:,1})

ans = 0.9514

max(A.Var1)

ans = 0.9514
