打开UniDBGrid的ClientEvents->ExtEvents属性，编辑Ext.grid.Panel的reconfig函数，输入如下代码就可以实现当UniDBGrid表格的ReadOnly属性为false、Options->dgRowSelect为false、Options->dgRowNumbers为false时（只要原表格的数据列，不带行号和勾选框等），按回车键就可以让光标横向切换表格列，到最后一列时将自动切换到下一条记录的第一列。

function reconfigure(sender, store, columns, oldStore, oldColumns, eOpts)
{

    var grid = sender;
    function fn() {
        var selModel = grid.getSelectionModel();
        var _row = selModel.getCurrentPosition().row;
        var _col = selModel.getCurrentPosition().column;

        if (grid.columnManager.columns[_col].isLastVisible) {
            _col = 0;
            _row += 1;
        } else {
            _col += 1;
        };

        setTimeout(function() {
            grid.getSelectionModel().select({
                row: _row,
                column: _col
            });
            grid.editingPlugin.startEdit(_row, _col);
        }, 10);
    };

    for (var i = 0; i < columns.length; i++) {
        var hasEditor = columns[i].getEditor();
        var ed = hasEditor || columns[i];

        if (columns[i].checkColumn) {
            columns[i].on('keydown', function(a, b, c, d, e) {
                if (e.getKey() == 13) {
                    fn();
                }
            })
        } else if (columns[i].rdonly) {
            ed.on('keydown', function(a, b, c, d, e) {
                if (e.getKey() == 13) {
                    fn()
                }
            })
        } else {
            ed.on('specialkey', function(field, e) {
                if (e.getKey() == 13) {
                    fn();
                }
            })
        }
    }
