Re: CellTable column and cell style

You can do it entirely with CSS. Extend CellTable.Resource and
CellTable.Style to provide your own .cellTableHeader. Change the
property of ".cellTableHeader" in CellTableStyle css file.

//CellTableStyle.css

.cellTableHeader
{
height: 25px;
border-bottom: 2px solid #60a6bf;
padding: 3px 25px;
text-align:right;
color: blue;
text-shadow: #ddf 1px 1px 0;
overflow: hidden;
cursor:pointer;
margin-right:0px;
border:solid 1px red;
background-image: url(bollon.gif);
background-repeat:no-repeat;
background-position:80% 50%;

}

// in java class.

CellTable<your_domain_object> studentTable = new
CellTable<your_domain_object>(15, GWT.<TableResources>
create(TableResources.class));
