How to reset the index in the increasing order

Hi,

I have the below table by time (old to latest), the first column is the index, but it resets some time. So, I want to add new column "NewIndex", and assign the index from 1 ~. Can anyone kindly help which command I should use here.

Table1:

2234  A  2015/3/4
2456  B  2015/3/5
4567  G  2015/3/6
4673  F  2015/3/7
2  A  2015/3/8
5  F  2015/3/9

and my output I want as below:

 1  2234  A  2015/3/4
 2  2456  B  2015/3/5
 3  4567  G  2015/3/6
 4  4673  F  2015/3/7
 5  2  A  2015/3/8
 6  5  F  2015/3/9

Amy thanks in advance.

Could you confirm that you mean the table() data type?

I want output table I have mentioned, from input (Table1), data is cell array. I just want to add one column to the Table1 (i.e, index 1~..).

There happens to be a MATLAB type called "table", so we needed to know if you meant that or if you meant "table" in a different sense. Your reference to cell array tells us that you did not mean the "table" data type.

Here is one way, assuming "C" is your original cell array.

nr = size(C,1);
CC = [num2cell((1:nr)'), C];
