I have the following table attached. In this table, I need 1st, 4th, 7th colum heading 'Time'. The 3rd and 6th colum heading should be 'NaN'. i tried the renamevars command but same name can not appear in tow different colum heading. How can I solve that problem.

Column names in a table must be distinct, so you're not going to be able to have multiple columns called 'Time', for instance.

As others have mentioned table variable names need to be unique. But let's say that was allowed then what are you trying to do after renaming the variables? Looking at the data it seems that you have 3 different tables and you are sort of using the NaN variables as a "separator". If all this is just for display purposes then you can try some of the workarounds suggested in other answers but if there is some workflow that follows the renaming process then describing that might lead to other useful answers.

I would just name the ‘Time’ variables as ‘Time1’, ‘Time2’ and ‘Time3’ to match the ‘v’ columns. The NaN columns are likely not necessary.

You can't have identical column names. If it's just for display purposes, you could add whitespace.

t1 = rand(3,1);
t2 = rand(3,1);
tbl = table(t1,t2,'VariableNames',["time","time "])
tbl = 3×2 table
     time       time  
    _______    _______

    0.77625      0.866
    0.72336     0.8574
      0.795    0.48366
