java - JTable with axis -

i'm fiddling around jtable, , want make table has letters a-p row names, , number 1-24 column names (it doesn't matter data type are). not matter if these row , column names inside table or external axis (whatever simpler).

my current attempt name string[] row , column names, , string[][] actual content. can't find out how merge valid format creating jtable. current code (that not work) following:

    // create table     string[] columnnames = {"", "1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12",                               "13", "14", "15", "16", "17", "18", "19", "20", "21", "22", "23", "24"                              };      string[] rownames = {"a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p"};      string[][] compoundnames = new string[25][16];      object[][] platedata = {rownames, compoundnames};      table = new jtable(platedata, columnnames);     table.setborder(new lineborder(new color(0, 0, 0)));     table.setbounds(10, 11, 564, 440);     contentpane.add(table); 

suggested solutions not have follow concept thought. said, simplest possible way make need, appreciated.

• string[][] compoundnames = new string[25][16]; should string[][] compoundnames = new string[16][25]; (no. elements columnnames , rownames)

• for basic informations required read oracle tutorial how use tables
