> [Writing Without Creating Objects] SimpleColumnWidthStyleStrategy can set
a fixed width for all columns; Can automatic column span be set or width be set
separately for each column?
You can use `AbstractHeadColumnWidthStyleStrategy` to customize.
Like:
```java
class CustomColumnWidthStyleStrategy extends
AbstractHeadColumnWidthStyleStrategy {
private final Map<Integer, Integer> headWidthMap;
CustomColumnWidthStyleStrategy(Map<Integer, Integer> headWidthMap) {
this.headWidthMap = headWidthMap;
}
@Override
protected Integer columnWidth(Head head, Integer columnIndex) {
return headWidthMap.get(columnIndex);
}
}
```
```java
List<List<String>> head = List.of(
List.of("Number"),
List.of("Name"),
List.of("Age")
);
Map<Integer, Integer> headWidthMap = new HashMap<>();
// for "Number"
headWidthMap.put(0, 10);
// for "Name"
headWidthMap.put(1, 20);
// for "Age"
headWidthMap.put(2, 30);
FastExcel.write(file)
.head(head)
.registerWriteHandler(new
CustomColumnWidthStyleStrategy(headWidthMap))
.sheet()
.doWrite(Collections.emptyList());
```
