find value in a table

[Esther.Lopez]

I have a table, with two columns. Both column contains strings. The
first one is an indicator, and the second one the value of this
indicator. The format is like this:
      indicator1   value1
      indicator2   value2
How can I find in this table the string "inidicator1" and return the
corresponding "value1"? thank you very much for your help
