定义动态单元格范围 [英] define dynamic cell range
问题描述
我正在使用APACHE POI进行条件格式设置.我得到txt文件作为输入,然后将其转换为工作表,然后执行条件格式.现在,第一列和标题是我不会对其进行任何格式设置的文本.我必须对其余单元格进行条件格式化,例如B2:I10(但它会不断变化).如何动态定义单元格范围.
I am using APACHE POI for conditional formatting. I get txt file as input and i convert it into worksheet and then perform the conditional formatting. Now, the first column and header are text on which I wont do any formatting. I have to do conditional formatting on rest of the cells, like B2:I10(but it would keep changing) How can i define the cell range dynamically.
当前,我有
CellRangeAddress[] my_data_range = {CellRangeAddress.valueOf("B2:I10")};
my_cond_format_layer.addConditionalFormatting(my_data_range,my_rule1)
我如何动态定义my_data_range,而将第一列和第一行放在一边.
how would i define my_data_range dynamically, keeping first column and row aside.
推荐答案
根据我的理解,我将问题分为两个部分.
As per my understanding, I am breaking the problem in two parts.
首先:-需要知道我们动态拥有数据的单元格范围地址
First:- need to know the cell range address in which we have data dynamically
第二个:-重新定义单元格范围地址.
Second:- re-define the cell range address.
优先解决方案:动态获取需要引用范围的单元格范围.
Solution of First: get cell range dynamically that need to refer in range.
您可以轻松获得数据的第一个单元格(数据的第一行/第一列)(说A3)和最后一个单元格(最后一行/最后一列)(例如F9)
You can easily get the first cell (first row/first column of data) of the data (Say its A3) and last cell (last row/last column) (say its F9)
如果您有任何单元格,则可以轻松地从
If you have any cell you can easily get its reference from
cell.getReference(); //will give you A3
现在我们需要使用简单的字符串操作将A和3分开
Now we need to seperate A and 3 using simple string operation
char startCellColRef = cell.getReference().toString().charAt(0); // will Give you A
int startCellRowRef = cell.getReference().toString().charAt(1); // will give you 3
使用相同的方法也可以获取结束索引.
Using same way you can get the end index as well.
秒的解决方案:动态更改单元格引用.
Solution of Second: Changing the cell references dynamically.
Name reference = wb.getName("NameReferenceInExcelSheet");
referenceString = sheetName+"!$"+startCellColRef+"$"+startCellRowRef+":$"+endCellColRef+"$"+endCellRowRef;
reference.setRefersToFormula(referenceString);
