C#新手在这里！
我需要创建一个小型控制台应用程序来将CSV文件转换为XLSX文件.
我有我的所有样式和数据,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
>将列A和C设置为宽度30
>将列D设置为宽度20

解决方法
要设置列宽,需要创建一个
Columns元素,该元素可以包含一个或多个
Column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适用的第一列和最后一列(包括).
在您的示例中,您需要定义两个Column实例,一个Min = 1,Max = 2,另一个Min和Max都设置为4(Min和Max是数字,A = 1,B = 2等).
需要将Column集合添加到SheetData元素之前的Worksheet中.
在stylesPart.Stylesheet.Save()之后添加以下代码;但在var sheetData = wsPart.Worksheet.AppendChild(new SheetData())之前;应该达到你的目标：
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);
注意1：Column类未涵盖的任何列都将具有默认宽度.
