我同意Scripto的答案。另一种方法是，在列定义中添加cellrenderer函数。

例如：

var cellsrenderer = function (row, columnfield, value, defaulthtml, columnproperties) {

            var theStatus = $("#jqxgrid").jqxGrid('getrowdata', row).StatusID;
            if (theStatus == 0) {
                return '<span style="margin: 4px;float: ' + columnproperties.cellsalign + ';color: #ff0000;font-weight: bold">' + value + '</span>';
            }
            else if (theStatus == 2) {
                return '<span style="margin: 4px;float: ' + columnproperties.cellsalign + ';color: #006638;font-weight: bold">' + value + '</span>';
            }
            else if (theStatus == 3) {
                return '<span style="margin: 4px;float: ' + columnproperties.cellsalign + ';color: #9B30FF;font-weight: bold">' + value + '</span>';
            }
        };

所以我们的列定义如下所示。

columns: [ { text: 'Number', datafield: 'InvoiceNumber', width: 50, cellsalign: 'right', cellsrenderer: cellsrenderer }]

我希望这会有所帮助。
