Qt uses xlsx to operate common functions and analysis of excel tables, draw border lines, automatically wrap lines, etc.

QXlsx::Document  xlsx;

1. Set column width or row height:

函数原型：
bool Document::setColumnWidth(int column, double width)
示例：
xlsx.setColumnWidth(第几列, 列宽); 

函数原型：
bool Document::setColumnWidth(int colFirst, int colLast, double width)
示例：
xlsx.setColumnWidth(开始列, 结束列, 列宽);

xlsx.setRowHeight(第几行, 行高); 
xlsx.setRowHeight(第几行, 结束行, 行高);

1.1 Write to the form

函数原型：
bool write(const CellReference &cell, const QVariant &value, const Format &format = Format());
参数1：单元格名；参数2：单元格的值；参数3：单元格格式
xlsx.write("A1", "FB3：电力安全工器具台账");
合并单元格：
xlsx.mergeCells("A1:N1", titleFormat);

2. Set the cell style:

QXlsx::Format titleFormat;

2.1 Set vertical alignment format

函数原型：
void Format::setVerticalAlignment(VerticalAlignment align)
示例：
titleFormat.setVerticalAlignment(Format::VerticalAlignment::AlignVCenter);//格式垂直居中
垂直对齐各种样式如下：
	enum VerticalAlignment {
    
    
		AlignTop, 		//顶端对齐
		AlignVCenter,	//垂直居中
		AlignBottom,	//底部对齐
		AlignVJustify,	//两端对齐
		AlignVDistributed
	};

2.2 Set the horizontal alignment format

示例：
titleFormat.setHorizontalAlignment(Format::VerticalAlignment::AlignLeft);
水平对齐各种样式如下：
    enum HorizontalAlignment {
    
    
        AlignHGeneral,
        AlignLeft,	//左对齐
        AlignHCenter,//水平居中对齐
        AlignRight,	//右对齐
        AlignHFill,
        AlignHJustify,
        AlignHMerge,
        AlignHDistributed
    };

2.3 Font size and boldness

titleFormat.setFontBold(true); //加粗
titleFormat.setFontSize(8);	//字体大小为8

As shown in the following rain, some contrasts are bold and not added, the second and third lines in the middle are 14 fonts, and the rest are 8 fonts

2.3 Set the border style, automatic line wrapping, etc.

Format headerFormat;

Effects of not setting:

add thin border

headerFormat.setBorderStyle(Format::BorderThin);

word wrap

headerFormat.setTextWarp(true);//自动换行

After setting:

the border style is as follows:

    enum BorderStyle {
    
    
        BorderNone, //无边框，默认
        BorderThin,	//薄边框
        BorderMedium,
        BorderDashed, //虚线边框
        BorderDotted, //点线边框
        BorderThick,
        BorderDouble,
        BorderHair,
        BorderMediumDashed,
        BorderDashDot,
        BorderMediumDashDot,
        BorderDashDotDot,
        BorderMediumDashDotDot,
        BorderSlantDashDot
    };
