如何让包装的列标题水平对齐？

Question

我正在 Excel 电子表格上创建一个“列标题行”，最终看起来像这样：

请注意，跨越多条“行”的列标题在其单元格内是如何不水平对齐的。最后一条“线”似乎很好地居中，但它之前/之上的那些是偏离中心的。例如，对于“Member Item Code”，“Member”way 离左边太远，“Item”也离左边太远（但不太严重），而“Code”看起来很完美.但是我的代码显然不是很完美。

我am将“中心”的水平对齐应用到这些单元格：

var unitHeaderCell = (Excel.Range)_xlSheet.Cells[rowToPopulate, DETAIL_UNIT_COL];
unitHeaderCell.Value2 = "Unit";

var custNumHeaderCell = (Excel.Range)_xlSheet.Cells[rowToPopulate, DETAIL_CUSTNUM_COL];
custNumHeaderCell.Value2 = String.Format("Customer{0}Number", Environment.NewLine);
custNumHeaderCell.HorizontalAlignment = Excel.XlHAlign.xlHAlignCenter;
custNumHeaderCell.WrapText = true;

var custNameHeaderCell = (Excel.Range)_xlSheet.Cells[rowToPopulate, DETAIL_CUSTNAME_COL];
custNameHeaderCell.Value2 = String.Format("Customer{0}Name", Environment.NewLine);
custNameHeaderCell.HorizontalAlignment = Excel.XlHAlign.xlHAlignCenter;
custNameHeaderCell.WrapText = true;

var memberItemCodeHeaderCell = (Excel.Range)_xlSheet.Cells[rowToPopulate, DETAIL_MEMBERITEMCODE_COL];
memberItemCodeHeaderCell.Value2 = String.Format("Member{0}Item{0}Code", Environment.NewLine);
memberItemCodeHeaderCell.HorizontalAlignment = Excel.XlHAlign.xlHAlignCenter;
memberItemCodeHeaderCell.WrapText = true;
memberItemCodeHeaderCell.ColumnWidth = DETAIL_MEMBERITEMCODE_COL_WIDTH;

var qtyHeaderCell = (Excel.Range)_xlSheet.Cells[rowToPopulate, DETAIL_QTY_COL];
qtyHeaderCell.Value2 = "Qty";

var bidPriceHeaderCell = (Excel.Range)_xlSheet.Cells[rowToPopulate, DETAIL_BIDPRICE_COL];
bidPriceHeaderCell.Value2 = "Bid Price";

我必须怎么做才能使这些词的所有居中（不仅仅是最后一个词）？

Answer 1

你不需要在单词之间添加Environment.NewLine，你可以简单地在单词之间使用空格并包裹列的内容，并根据列宽显示多行。

在下面的代码中，我将范围内的所有单元格设置为环绕文本并垂直和水平居中。

也只是为了测试，我设置了第 5 列的列宽。

//Using
using XL = Microsoft.Office.Interop.Excel;

//Code
XL.Application application = new XL.Application();
application.Visible = true;
var book = application.Workbooks.Add();
var sheet = book.Worksheets[1];

sheet.Cells[1, 1].Value2 = "Unit";
sheet.Cells[1, 2].Value2 = "Customer Number";
sheet.Cells[1, 3].Value2 = "Customer Name";
sheet.Cells[1, 4].Value2 = "Member Item Code";
sheet.Cells[1, 5].Value2 = "Qty";
sheet.Cells[1, 5].ColumnWidth = 30;
sheet.Cells[1, 6].Value2 = "Bad Price";

var range = sheet.Range("A1", "F1");
range.VerticalAlignment = XL.XlVAlign.xlVAlignCenter;
range.HorizontalAlignment = XL.XlHAlign.xlHAlignCenter;
range.WrapText = true;

这是默认字体设置的结果：

这是使用自定义字体设置的结果：

range.Font.Name = "Tahoma";
range.Font.Bold = true;
range.Font.Size = 9;
