Printing out strings to align to match it's placement in another String

I need to print out strings that align to match it's placement in another String when data is grouped together. For instance:

I have an ArrayList of Strings containing:

[0]    "data1 data2 data3"
[1]    "data1 data2 data3"
[2]    "data3"
[3]    "data4"
[4]    "data4 data5"

I want the output to be

[0]    "data1 data2 data3"
[1]    "data1 data2 data3"
[2]    "            data3"
[3]    "data4"
[4]    "data4 data5"
