本文整理了Java中org.apache.poi.ss.usermodel.Row.getCell方法的一些代码示例，展示了Row.getCell的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Row.getCell方法的具体详情如下：
包路径：org.apache.poi.ss.usermodel.Row
类名称：Row
方法名：getCell

Row.getCell介绍

[英]Get the cell representing a given column (logical cell) 0-based. If you ask for a cell that is not defined....you get a null.
[中]从0获取表示给定列（逻辑单元）的单元。如果你要一个未定义的单元格。。。。你会得到一个空值。

/**
 * Return the cell, without taking account of merged regions.
 * <p>
 * Use {@link #getCellWithMerges(Sheet, int, int)} if you want the top left
 * cell from merged regions instead when the reference is a merged cell.
 * <p>
 * Use this where you want to know if the given cell is explicitly defined
 * or not.
 *
 * @param sheet The workbook sheet to look at.
 * @param rowIx The 0-based index of the row.
 * @param colIx The 0-based index of the cell.
 * @return cell at the given location, or null if not defined
 * @throws NullPointerException if sheet is null
