MATLAB: Last row in a matrix is not computing :(

So i have a homogenous numeric array as shown below. I converted this array to a table using the array2Table function. What is shown below is simply the variabe names being applied to the array. I have column names but I would like to have row names as well. Is it the fact that the array is of one variable class that I cant do this?

T = array2table(C,'RowNames',{'','T0','T1','T2','T3','T4'},'VariableNames' ,{'to','t1','t2','t3','t4','t5','t6','t7','t8','t9','t10'})




T =

  6×11 table

    to       t1        t2        t3        t4        t5        t6        t7        t8        t9       t10

The errors that Im getting here are:
