* - loop = array to loop through
18
* - cols = number of columns

* - cols = number of columns, comma separated list of column names
19
* or array of column names
19
20
* - rows = number of rows
20
21
* - table_attr = table attributes
22
* - th_attr = table heading attributes (arrays are cycled)
21
23
* - tr_attr = table row attributes (arrays are cycled)
22
24
* - td_attr = table cell attributes (arrays are cycled)
23
25
* - trailpad = value to pad trailing cells with
26
* - caption = text for caption element
24
27

25
28
* - hdir = horizontal direction (default: "right", means left-to-right)
26
29
* - inner = inner loop (default "cols": print $loop line by line,
32
35
* {table loop=$data}
