可以使用 NPOI 的 `ICellRange` 接口来获取表格的列数量。具体步骤如下:
1. 获取表格对象
```c#
var workbook = new HSSFWorkbook(file);
var sheet = workbook.GetSheetAt(0);
```
2. 获取表格的第一行
```c#
var headerRow = sheet.GetRow(0);
```
3. 使用 `ICellRange` 接口获取列数量,代码如下:
```c#
int columnCount = 0;
foreach (var cellRange in headerRow.MergedCells)
{
columnCount += cellRange.LastColumn - cellRange.FirstColumn + 1;
}
columnCount += headerRow.LastCellNum - headerRow.FirstCellNum;
```
首先遍历所有合并的单元格,将每个合并单元格的列数累加起来,然后再加上未合并的单元格的列数即可得到表格的总列数。
完整代码示例:
```c#
var workbook = new HSSFWorkbook(file);
var sheet = workbook.GetSheetAt(0);
var headerRow = sheet.GetRow(0);
int columnCount = 0;
foreach (var cellRange in headerRow.MergedCells)
{
columnCount += cellRange.LastColumn - cellRange.FirstColumn + 1;
}
columnCount += headerRow.LastCellNum - headerRow.FirstCellNum;
Console.WriteLine($"The number of columns in the table is {columnCount}");
```
