escape character in dhtmlGrid

I have a grid with a few columns “Editable”.



When I edit a cell with the character “>” in it,it display like “>”,how can I do something prevent it from changing “>”

to “>”?

If you want to preserve special characters ( < > & ), you need to use text based column types ( default column types are html based )
Use next types
ro -> rotxt
ed -> edtxt
txt -> txttxt
coro -> corotxt

It doesn’t work! Firstly I set the column type “ReadOnly”,then I set it to “Editable”,I doubleclick the cell,the character “>” changed to “>”,and I don’t want the change.so please give me an effective method.Thanks!
