Read data from table step by step

Hello,

I created table inside of .VI, where I will later set:

1. column: time in seconds

2. column: voltage in V

3. column:current limit in A

These data will be sent to programmable power supply (WISA WRITE or DLL...) where I want to make "step by step operation". I also created graphical representation of just few data so when someone will programming procedure will know how sequence look.

1. Can anyone help me how I can create for example value in first row will mean time (wait ) then second value in first row voltage (so for example wait for 5 seconds at voltage 13 V ). After time expired I want that it automatically go to second row.

2. how can I change code that I can insert "relative" seconds, like:

time(s)     voltage (V)

0                   5

5                   13

10                14

3                   13

that means->  at 0 s voltage is 5V then for 5 seconds at voltage 13V than for 10 seconds at voltage 14 and then for 3 seconds at voltage 13V.

thanks
