patch to table component

[Yunfeng Hou <ho...@yahoo.com>]

I found contrib:table very useful, however, I do not
like the way how to render column block. It will force
to use name as fooColumnValue to replace the default
column renderer. Even worse, if I have two table
components on the same page, column names chould have
conflicts. So I decide to patch it a little to avoid
this.
Here's what I did:
1. add ColumnBlock component, which has table, column
and isHeader parameters
2. For TableColumnModelSourceImpl, add logic to set
column renders with ColumnBlock defined.

Now the template looks like:

<table jwcid="persons@contrib:Table"
source="ognl:rows"	columns="name,age">
    <span jwcid="name@contrib:ColumnBlock"
table="persons">
         <span jwcid="@Insert"
value="ognl:components.persons.tableRow.name.toUpperCase()"
/> 
     </span>
    <span jwcid="@contrib:ColumnBlock" table="persons"
column="age" >
         <span jwcid="@Insert"
value="ognl:components.persons.tableRow.age*2" /> 
     </span>
</table>

hope this is useful.
