您好！
我正在评估使用 Aspose.Cells 来处理 Excel 文件的能力，并有一个具体的需求想要咨询。我的 Excel 文件中的某个sheet表中包含多个独立的表格（连续或者非连续的数据区域），我想知道 Aspose.Cells 是否提供了识别每个表格表头信息的功能？特别地，我希望能够获取每个表格表头所占据的行数。
例如，在一个工作表中可能存在两个或更多的数据区域，每个区域有自己的表头（可能由一行或多行组成）。请问 Aspose.Cells 是否能够自动检测这些信息？如果可以的话，请问是否有相关的 API 或者代码示例可供参考？
非常感谢您的帮助！
Cause
Aspose.Cells does not have a built-in feature specifically designed to automatically detect and extract header information from multiple independent tables within a single worksheet. However, you can implement a custom solution to identify these headers based on certain criteria, such as formatting or specific row content.
Solution
To achieve this, you can iterate through the rows of the worksheet, checking for characteristics that typically define headers (like bold font, specific background colors, or specific text patterns). Once identified, you can count the number of rows that make up each header.
Code
Here’s a basic example in C# to get you started:
using Aspose.Cells;
public void ExtractTableHeaders(string filePath)
{
// Load the workbook
Workbook workbook = new Workbook(filePath);
Worksheet worksheet = workbook.Worksheets[0]; // Access the first worksheet
int rowCount = worksheet.Cells.MaxDataRow + 1; // Get total number of rows
List<int> headerRows = new List<int>();
for (int row = 0; row < rowCount; row++)
{
// Check if the row is a header (you can customize this condition)
if (IsHeaderRow(worksheet.Cells, row))
{
headerRows.Add(row);
// Optionally, count how many rows the header spans
int headerSpan = CountHeaderRows(worksheet.Cells, row);
Console.WriteLine($"Header found at row {row}, spanning {headerSpan} rows.");
}
}
}
private bool IsHeaderRow(Cells cells, int row)
{
// Example condition: Check if the first cell in the row is bold
return cells[row, 0].GetStyle().Font.IsBold;
}
private int CountHeaderRows(Cells cells, int startRow)
{
int count = 0;
while (startRow + count < cells.MaxDataRow + 1 && IsHeaderRow(cells, startRow + count))
{
count++;
}
return count;
}
Next Steps
IsHeaderRow method to fit your specific criteria for identifying headers.This solution should effectively help you extract header information from your Excel worksheets. Let me know if you need any further clarification!

在Excel里，ListObject（表格）只会有一行表头，PivotTable（透视表）的表头会根据数据分布不同发生变化。请参考以下样例代码获取表格和透视表的范围并查看附件。sample.zip (15.0 KB)
.NET样例代码如下：
Workbook workbook = new Workbook(filePath + "sample.xlsx");
WorksheetCollection sheets = workbook.Worksheets;
foreach (Worksheet sheet in sheets)
{
Console.WriteLine(sheet.Name + "============================");
ListObjectCollection listObjects = sheet.ListObjects;
foreach (ListObject table in listObjects)
{
if (table.ShowHeaderRow)
{
Console.WriteLine("Table Name: " + table.DisplayName + " table header row: " + table.StartRow);
}
Console.WriteLine("Table data range: " + table.DataRange.ToString());
}
PivotTableCollection pivotTables = sheet.PivotTables;
foreach (PivotTable pivotTable in pivotTables)
{
Console.WriteLine("Pivot Table Name: " + pivotTable.Name);
Console.WriteLine("Pivot Table column range: " + pivotTable.ColumnRange.ToString());
Console.WriteLine("Pivot Table row range: " + pivotTable.RowRange.ToString());
Console.WriteLine("Pivot Table data body range: " + pivotTable.DataBodyRange.ToString());
Console.WriteLine("Pivot Table table range(doesn’t include page fields): " + pivotTable.TableRange1.ToString());
Console.WriteLine("Pivot Table table range(include page fields): " + pivotTable.TableRange2.ToString());
}
}
输出结果：
Sheet1============================
Table Name: Table1 table header row: 0
Table data range: Aspose.Cells.Range [ Sheet1!A2:D4 ]
Table Name: Table2 table header row: 6
Table data range: Aspose.Cells.Range [ Sheet1!G8:J10 ]
Pivot Table Name: PivotTable1
Pivot Table column range: Aspose.Cells.CellArea(D16:G17)[15,3,16,6]
Pivot Table row range: Aspose.Cells.CellArea(C18:C20)[17,2,19,2]
Pivot Table data body range: Aspose.Cells.CellArea(D18:G20)[17,3,19,6]
Pivot Table table range(doesn’t include page fields): Aspose.Cells.CellArea(C16:G20)[15,2,19,6]
Pivot Table table range(include page fields): Aspose.Cells.CellArea(C14:G20)[13,2,19,6]
Sheet2============================
Table Name: Table24 table header row: 3
Table data range: Aspose.Cells.Range [ Sheet2!C5:F7 ]
Pivot Table Name: PivotTable2
Pivot Table column range: Aspose.Cells.CellArea(D14:F15)[13,3,14,5]
Pivot Table row range: Aspose.Cells.CellArea(C16:C19)[15,2,18,2]
Pivot Table data body range: Aspose.Cells.CellArea(D16:F19)[15,3,18,5]
Pivot Table table range(doesn’t include page fields): Aspose.Cells.CellArea(C14:F19)[13,2,18,5]
Pivot Table table range(include page fields): Aspose.Cells.CellArea(C12:F19)[11,2,18,5]

此外，如果您的工作表中包含表格或列表对象，您可以利用并浏览ListObjects以获取所需信息，具体内容请参阅关于表格/列表对象的相关章节。如果您有普通或随机数据，我们需要区分哪些行是标题行。请将包含表格的模板Excel文件压缩后附上，我们将进一步查看以提取标题行信息。
