Hi, I want to convert my table 'T'(1000 X 70) to an array 'A'. The table 'T' contains 70 different column headers. I again want to convert the array 'A' back to table 'T' without losing the column headers. How is it possible to do without manually entering all the 70 column headers as given below:

T = array2table(A,...
    'VariableNames',{'Feet','Inches','Centimeters'})
