Preface

This time, let's implement compound format tables and variable column tables , The effect is as follows

---

The following is the main body of this article , The following cases can be used for reference

Compound format table

One 、 Take apart word xml Document labels

As required, we can send the form Split by behavior unit Table rows in four formats ;
We are at this time xml These four lines are reserved in the template file for use .

Table traversal logic

<w:tbl>
<!--  Header row  begin -->
       <w:tr>...</w:tr>
<!--  Header row  end -->

       <#list complexTable.rows as tableRow>
            <#if !tableRow_has_next>
              	<!--  The last line of the table  begin -->
            	<w:tr>...</w:tr>
            	<!--  The last line of the table  end -->
           <#elseif tableRow_has_next && tableRow_index == 0 >
                <!--  First row of table content  begin -->
				<w:tr>...</w:tr>
                <!--  First row of table content  end -->

           <#else >
				<!--  Middle row of table content  begin -->
				<w:tr>...</w:tr>
				<!--  Middle row of table content  end -->
           </#if>
            
       </#list>
  </w:tbl>

The above code logic can be compatible with a piece of data , In the case of two pieces of data and multiple lines of data, the format will not be disordered , Please see the following test results for the operation effect .

Data structure definition

{
    
	"columns": [
		" Name 1",
		" Name 2"
	],
	"rows": [
		{
    
			"cell1": " Xiaohong ",
			"cell2": " Woman "
		},
		{
    
			"cell1": " Xiao Ming ",
			"cell2": " male "
		}
		......

		{
    
			"cellFinal": " Cheerleading , I can define fields at will , As long as the composite template split logic "
		}
	]
}

row The data structure of the last row is different from the above , In fact, it can also be defined as the same , Just according to our disassembly logic , The last line takes only one field , So I defined another structure to store , In fact, as long as you can get it in the template .

Two 、 result

A line of data

Two lines of data

Multi row data

Variable length column format table

A table with an indefinite number of columns .

Disassembly logic

Tables with variable length columns are mainly Add another one inside the line list loop , then Control the format in columns , Generally, you only need to control the leftmost and last columns of each row .

<w:tbl>
<!--  Header row  begin -->
  <w:tr>
	<#list complexTable.columns as column>
		<w:tc>...
		<w:t>${column}</w:t>
		...</w:tc>
	</#list>
  </w:tr>
<!--  Header row  end -->

       <#list complexTable.rows as tableRow>
            <#if !tableRow_has_next>
              	<!--  The last line of the table  begin -->
            	<w:tr>...
            		<#list tableRow as cell>
						<w:tc>...
						            		<!--  If the outer border of the table is different from the inner border, you need to add ifelse Code , First column adjust left border , The last column adjusts the right border ; <w:tcBorders> <w:top w:val="single" w:sz="8" wx:bdrwidth="20" w:space="0" w:color="000000"/> <w:left w:val="dash-dot-stroked" w:sz="24" wx:bdrwidth="60" w:space="0" w:color="auto"/> <w:bottom w:val="dash-dot-stroked" w:sz="24" wx:bdrwidth="60" w:space="0" w:color="auto"/> <w:right w:val="single" w:sz="8" wx:bdrwidth="20" w:space="0" w:color="000000"/> </w:tcBorders> -->
						<w:t>${cell}</w:t>
						...</w:tc>
					</#list>
				...</w:tr>
            	<!--  The last line of the table  end -->
           <#elseif tableRow_has_next && tableRow_index == 0 >
                <!--  First row of table content  begin -->
				<w:tr>...</w:tr>
                <!--  First row of table content  end -->

           <#else >
				<!--  Middle row of table content  begin -->
				<w:tr>...</w:tr>
				<!--  Middle row of table content  end -->
           </#if>
            
       </#list>
  </w:tbl>

Data structure definition

{
    
	"columns": [
		" Name 1",
		" Name 2"
	],
	"rows": [
		[
			" data 1",
			" data 2"
		],
		[
			" data 1",
			" data 2"
		]
	]
}

summary

In the last chapter, we talked about the generation method of fixed format tables and pictures ; In this chapter, we explain how to generate “ Compound format table ” and “ Variable column table ”, This is enough for me to deal with a large number of application scenarios , If there are more complex scenes , for instance “ Variable column plus compound format, and then some columns need fixed width ” Such a need , We can combine the above solutions , Close test available .
