Question

我已经使用Open XML在excel中导出了数据，现在我需要根据单元格值为几列的单元格添加颜色。

我已从以下链接获取帮助进行导出： http://justgeeks.blogspot.com/2012/03/writing-large-amounts-of-data-from.html

任何人都可以帮我处理着色部分。我的数据在数据表中。

        {
            var dataRowView = e.Row.DataItem as DataRowView;
            DataRow row = dataRowView.Row;

            var Current = (row["Dosage"] as int?) ?? null;


            if (Current != null)
            {
                if (Current >= 1 && Current < 10)
                    e.Row.Cells[1].BackColor = Color.Green;
