我需要创建一个小型控制台应用程序，将CSV文件转换为XLSX文件。
我的所有样式和数据都有效，但我想在某些列上设置不同的（默认）宽度。经过一天的搜索和阅读后，我仍然无法弄清楚如何让它发挥作用。
作为一个例子，我想
任何帮助或提示都会很棒。 我的代码现在在

要设置列宽，您需要创建一个Columns元素，该元素可以包含一个或多个Column个子元素。
每个Column类都可以应用于Excel文件中的多个列。 Min和Max属性定义Column适用于（包括）的第一列和最后一列。
在您的示例中，您需要定义两个Column个实例，一个包含Min=1和Max=2，另一个包含Min和Max设置为4（Min和Max是数字，A = 1，B = 2等。）
Columns集合需要添加到Worksheet元素之前的SheetData。
在stylesPart.Stylesheet.Save();之后var sheetData = wsPart.Worksheet.AppendChild(new SheetData());之前添加以下代码可以实现您的目标：
Columns columns = new Columns();
columns.Append(new Column() { Min = 1, Max = 3, Width = 20, CustomWidth = true });
columns.Append(new Column() { Min = 4, Max = 4, Width = 30, CustomWidth = true });
wsPart.Worksheet.Append(columns);
注1：Column类未涵盖的任何列都将具有默认宽度。
注意2：应指定列的所有属性（Min，Max，Width，CustomWidth）。否则Excel将确定该文件已损坏。
