It's a common scenario to set custom css on <td> for specific column, for example, using columns: { field: "ScoreNumber", css: "right-align", title: "Score" } to get <td class='right-align'>, then I can make every every score field text-align: right. Maybe adjusting _tmpl: in Grid Widget as rowTemplate += "<td" + (column.css ? " class='" + column.css + "'" : "") + ">"; is a easy way to accomplish it.

You can accomplish that by: columns: [ { field: "ScoreNumber", attributes: { "class": "score-cell"}, .... }, ...
