ExcelReaderFactory，读取第一张表

ExcelReaderFactory是一个用于读取Excel文件的工厂类。它提供了一种简单而高效的方式来读取Excel文件中的数据，并将其转化为可供程序使用的格式。

java
import com.github.excelreaderfactory.ExcelReaderFactory;
import com.github.excelreaderfactory.model.SheetData;

java
String filePath = "path/to/excel/file.xlsx";
SheetData sheetData = ExcelReaderFactory.read(filePath, 0);

java
int rows = sheetData.getRows();
int columns = sheetData.getColumns();
List> data = sheetData.getData();
// 遍历数据并输出
for (List rowData : data) {
    for (String cellData : rowData) {
        System.out.print(cellData + "\t");
    }
    System.out.println();
}

java
import com.github.excelreaderfactory.ExcelReaderFactory;
import com.github.excelreaderfactory.model.SheetData;
public class ExcelReaderExample {
    public static void main(String[] args) {
        String filePath = "path/to/excel/file.xlsx";
        SheetData sheetData = ExcelReaderFactory.read(filePath, 0);
        int rows = sheetData.getRows();
        int columns = sheetData.getColumns();
        List> data = sheetData.getData();
        // 遍历数据并输出
        for (List rowData : data) {
            for (String cellData : rowData) {
                System.out.print(cellData + "\t");
            }
            System.out.println();
        }
    }
