How to store values from web browser table

On the first step you narrow down the row/column cell to read, I understand that you have this covered as your question is on how to store the value and not isolate to read.
On the second step you store the value in a variable that can reside in three different locations:
1-Project Suite
2-Project
3-Script 
In "Project Explorer" right click to Edit > Variables
One thing to keep in mind is the variable type and converting type.

In KeywordTests use the "Set Variable Value" Operations

In Script 

function Test1()
{
  var Var1;
  Var1 = "";
  Var1 = Aliases.browser.pageW3schoolsTryitEditor.frameIframeresult.cell.contentText;
  Log.Message("On screen value: " + Var1, "");
}
