Detailed Description

The HDynTable contains the collection of numeric or textual typed fileds referenced by names.\n
After you define the elements, you can easely set/get elements value referenced by it's name.
The HDynTable has many batch mathematical function to easely work with the all element together.
The mathematical functions only works on numeric elements, they don't affect the textual elements.

HDynTable t;
t.defN("a");
t.defN("b");
t.defS("t");
t["a"] = 10.2;
t["b"] = 3 * t["a"];
t.divide(t.sum());
t["b"] += 100;
t["t"] = "Texual data";

The HDynTable can dynamically build a QTableWidget from the elements you defined. (See HDynTableDispConnector)
You can define element with different column/row names, and the HDynTable will be generate the appropirate QTableWiget, It means: The same row named elements will appear in same row, if an element have unique rowname it will appear in separated row. The classes will automatically handles the refreshing the data in the memory. It means that the user changes will automatically apply on HDynTable's values. It also can handle the SQL query/update of the fileds. (See HDynTableSqlConnector)

...
//Create an empty dyntable and define the fields
HDynTable *dt = new HDynTable();
      //name    sqlf    rown    coln
dt->defN("appg" ,"appg" ,"Apple","Good");
dt->defN("appb" ,"appb" ,"Apple","Bad");
dt->defN("pearg","pearg","Pear" ,"Good");
dt->defN("pearb","pearb","Pear" ,"Bad");
dt->defN("plumg","plumg","Plum" ,"Good");
dt->defN("plumb","plumb","Plum" ,"Bad");
dt->defN("nut"  ,"nut"  ,"Nut"  ,"Good");
HSqlHandler *sql=new HSqlHandler();
//Connects the dyntable to the sql table
HDynTableSqlConnector *sql_conn = new HDynTableSqlConnector(dt,sql,"mytable");
//Initialize the ui's table with this dyntable
HDynTableDispConnector *disp_conn = new HDynTableDispConnector(dt,ui->table);
//We reads the values from sql. The gui will refresh automatically.
sql_conn->readSql();
//We want the sql table to be updated every time, when the user change a data on gui
connect(disp_conn,SIGNAL(dataChangedByGui()),sql_conn,SLOT(updateSql()));
...

The code above is generates a QTableWidget look like this:
