And reading the model of plugin_wiki I see that in def jqgrid the
parameters and you doc are divergent in fields -> columns and
col_widths -> ??? (I think):
@staticmethod
def jqgrid(table,fieldname=None,fieldvalue=None,col_widths='',
_id=None,fields='',col_width=80,width=700,height=300):
"""
## Embed a jqGrid plugin
- ``table`` is the table name
- ``fieldname``, ``fieldvalue`` are an optional filter
(fieldname==fieldvalue)
- ``_id`` is the "id" of the DIV that contains the jqGrid
- ``columns`` is a list of columns names to be displayed
- ``col_width`` is the width of each column (default)
- ``height`` is the height of the jqGrid
- ``width`` is the width of the jqGrid
"""
