  10. * Type: function<br>
  11. * Name: html_table<br>
  12. * Date: Feb 17, 2003<br>
  13. * Purpose: make an html table from an array of data<br>
  14. * Input:<br>
  15. * - loop = array to loop through
  16. * - cols = number of columns, comma separated list of column names
  17. * or array of column names
  18. * - rows = number of rows
  19. * - table_attr = table attributes
  20. * - th_attr = table heading attributes (arrays are cycled)
  21. * - tr_attr = table row attributes (arrays are cycled)
  22. * - td_attr = table cell attributes (arrays are cycled)
  23. * - trailpad = value to pad trailing cells with
  24. * - caption = text for caption element
  25. * - vdir = vertical direction (default: "down", means top-to-bottom)
  26. * - hdir = horizontal direction (default: "right", means left-to-right)
  27. * - inner = inner loop (default "cols": print $loop line by line,
  28. * $loop will be printed column by column otherwise)
  29. *
  30. *
  31. * Examples:
  32. * <pre>
  33. * {table loop=$data}
  34. * {table loop=$data cols=4 tr_attr='"bgcolor=red"'}
  35. * {table loop=$data cols="first,second,third" tr_attr=$colors}
