**===What it does===**

Wraps tabular data in an HTML table for easier viewing.

------

**===Headers===**

**Column numbers** - The header will show the order of the columns.

**Column names** - The header will show column names if the data file is a
specific type of tabular file that has column names in
Galaxy (such as *sam* or *taxonomy*). Otherwise, no header will be shown.

**Specify headers and subheaders** - This allows custom headers, which can span
multiple columns if subheaders are included. For example, the tabular file::

  1      2    3      4
  read1  100  12345  50
  read2  150  56789  60

...with the headers and subheaders::

  Query
    ID
    length
  Hit
    gi
    score

...would create an html table with the format:

+----------------+---------------+
|     Query      |      Hit      |
+-------+--------+-------+-------+
|  ID   | length |   gi  | score |
+=======+========+=======+=======+
| read1 |  100   | 12345 |  50   |
+-------+--------+-------+-------+
| read2 |  150   | 56789 |  60   |
+-------+--------+-------+-------+
