Question

我有一个axlsx文件，其中有一些创建行的逻辑。我在那里检查，当满足某个条件时，我想合并创建的最后一个单元格。我怎么能这样做？

我见过如何合并单元格的唯一方法是指定要合并的单元格：

sheet.merge_cells "A2:B2"

但如果我有动态工作表，我该如何合并最后一行的单元格？

Answer 1

Axlsx merge_cells接受一个字符串，如您的示例或单元格数组。在这种程度上，您可以使用rows，cols及其单元格集合来查找，并传入要合并的单元格数组。

类似的东西：

sheet.merge_cells sheet.rows.last.cells

供参考，这是有关Worksheet＃merge_cell

的文档

# Creates merge information for this worksheet.
# Cells can be merged by calling the merge_cells method on a worksheet.
# @example This would merge the three cells C1..E1    #
#        worksheet.merge_cells "C1:E1"
#        # you can also provide an array of cells to be merged
#        worksheet.merge_cells worksheet.rows.first.cells[(2..4)]
#        #alternatively you can do it from a single cell
#        worksheet["C1"].merge worksheet["E1"]
# @param [Array, string] cells
def merge_cells(cells)
  merged_cells.add cells
end

Answer 2

这是一种通用解决方案

 current_row = sheet.rows.count + 1
 merge_parameter= "A#{current_row}:F#{current_row}"
 sheet.merge_cells(merge_parameter)

Rails AXLSX gem尝试合并创建的最后一行的单元格
