cannot break word in table td

[tong123123]

In normal HTML, I have try, in a table, set

table-layout:fixed

then in td, set

white-space:normal;
word-wrap:break-word;

the long word can be broken to two line in IE9.
BUT when I use GWT 2.4 FlexTable, I set similar property.
there is a <div> inside <td> as I use new HTML(".....");
I try to apply

white-space:normal;
word-wrap:break-word;

inside the <td> and <div> of the fixed-layout table,
but the long word cannot be broken in IE9. what is the cause?

I found the solution, before I set the FlexTable

table-layout:fixed

then in td, set

white-space:normal;
word-wrap:break-word;

in column, I set

flexTable.getColumnFormatter().setWidth(0, "150px");
flexTable.getcolumnFormatter().setWidth(1, "200px");

 the word in td cannot be broken, after I add

flexTable.setWidth("350px");

the word in td can be broken!!
