What is the tag for floating table? i.e. 2 tables within a cell of a 
table may remain on side when screen width is larger and slide below one 
another when the browser width reduces?

e.g. In a newspaper column with the browser window in Full SIze the 
columns may appear as follows,

A News and B news are 2 tables with 1 row and 1 column
 <-----------Brwose Windows Width----------->
 <-cell width------>
 -----------------------------------------
 ------   -----    |          A
|  A   | | B    |  |          |
|  News| | News |  |         Smaller Cell Height
|      | |      |  |          |
|      | |      |  |          |
|      | |      |  |          |
 ------   -----    |          V
-------------------          ---

Now, when viewer reduces the Browser window width The B news should 
slide below B news,

<---Reduced Browser width------->
<-thiner->
----------------------------
 ------  |   A
|  A   | |   |
|  News| |   |
|      | |   |
|      | |   |
|      | |   Same Cell Unit Height now increased, width reduced to <-thiner->
 ------  |   |
   ----- |   |
  | B   ||   |
  | News||   |
  |     ||   |
  |     ||   |
  |     ||   |
   ----- |   v
---------   --

Conventional <td> creates the table one below another, it does not allow 
the table on side (when tables are created within a cell of a larger table)

Is there a new tag for it or facility in any other form of HTML?
