Citing statistical information presented in a table using data from a variety of sources? How do I cite information that I am presenting in a table (i.e. that I have created), when the statistics I have compiled are from different sources?

in the table text, there are small letters in superscript (a, b, c...)

the references are named below the table, again with the small letters in superscript, but all in one line
