篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Unity HTFramework框架（四十一）在编辑器内绘制美观且实用的表格窗口（TableView）相关的知识，希望对你有一定的参考价值。
TableView表格视图
使用TableView可以很方便的绘制表格视图，当然，实际上它就是使用了TreeView进行绘制而已，所以关于TreeView的一些信息我便不再讲解了，如有什么不明白的地方可以参考官方脚本手册。
使用
定义表格行
TableView的使用非常简单，首先，表格的数据对应了一个List集合，其中每一行对应集合中的每一个元素，所以，我们先自定义一个表格数据集合：
public class Student
{
public string name;
public Sex sex;
public int age;
public string grade;
public string address;
public GameObject entity;
public Color col;
public Texture headImage;
}
public enum Sex
{
Man,
Woman
}
List<Student> _students = new List<Student>();
定义表格列
然后，我们需要定义表格列对象TableColumn的集合，他告诉了TableView我们的表格需要绘制多少列，每列如何绘制数据等，如下，定义一个列，用于绘制数据类Student的name字段：
new TableColumn<Student>()
{
//如何绘制列头
headerContent = new GUIContent("姓名"),
//列的初始宽度
width = 100,
//是否支持排序
canSort = true,
//支持排序时的排序方法
Compare = (a, b) =>
{
return a.name.CompareTo(b.name);
},
//列的绘制方法，比如这一列是绘制Student的name字段
DrawCell = (cellRect, data, rowIndex, isSelected, isFocused) =>
{
data.name = EditorGUI.TextField(cellRect, data.name);
},
}
如此，便定义了表格中某一列的规则，我们依葫芦画瓢的加入Student的其他字段的列绘制规则：
List<TableColumn<Student>> _tableColumns = new List<TableColumn<Student>>();
_tableColumns.Add(new TableColumn<Student>()
{
headerContent = new GUIContent("姓名"),
width = 100,
canSort = true,
autoResize = false,
Compare = (a, b) =>
{
return a.name.CompareTo(b.name);
},
DrawCell = (cellRect, data, rowIndex, isSelected, isFocused) =>
{
data.name = EditorGUI.TextField(cellRect, data.name);
},
});
_tableColumns.Add(new TableColumn<Student>()
{
headerContent = new GUIContent("性别"),
width = 100,
canSort = true,
autoResize = false,
Compare = (a, b) =>
{
return a.sex.CompareTo(b.sex);
},
DrawCell = (cellRect, data, rowIndex, isSelected, isFocused) =>
{
data.sex = (Sex)EditorGUI.EnumPopup(cellRect, data.sex);
},
});
_tableColumns.Add(new TableColumn<Student>()
{
headerContent = new GUIContent("年龄"),
width = 100,
canSort = true,
autoResize = false,
Compare = (a, b) =>
{
return a.age.CompareTo(b.age);
},
DrawCell = (cellRect, data, rowIndex, isSelected, isFocused) =>
{
data.age = EditorGUI.IntField(cellRect, data.age);
},
});
_tableColumns.Add(new TableColumn<Student>()
{
headerContent = new GUIContent("班级"),
width = 100,
canSort = true,
autoResize = false,
Compare = (a, b) =>
{
return a.grade.CompareTo(b.grade);
},
DrawCell = (cellRect, data, rowIndex, isSelected, isFocused) =>
{
data.grade = EditorGUI.TextField(cellRect, data.grade);
},
});
_tableColumns.Add(new TableColumn<Student>()
{
headerContent = new GUIContent("家庭住址"),
width = 100,
canSort = true,
autoResize = false,
Compare = (a, b) =>
{
return a.address.CompareTo(b.address);
},
DrawCell = (cellRect, data, rowIndex, isSelected, isFocused) =>
{
data.address = EditorGUI.TextField(cellRect, data.address);
},
});
_tableColumns.Add(new TableColumn<Student>()
{
headerContent = new GUIContent("实体"),
width = 100,
canSort = false,
autoResize = false,
Compare = null,
DrawCell = (cellRect, data, rowIndex, isSelected, isFocused) =>
{
data.entity = (GameObject)EditorGUI.ObjectField(cellRect, data.entity, typeof(GameObject), true);
},
});
_tableColumns.Add(new TableColumn<Student>()
{
headerContent = new GUIContent("颜色"),
width = 100,
canSort = false,
autoResize = false,
Compare = null,
DrawCell = (cellRect, data, rowIndex, isSelected, isFocused) =>
{
data.col = EditorGUI.ColorField(cellRect, data.col);
},
});
_tableColumns.Add(new TableColumn<Student>()
{
headerContent = new GUIContent("头像"),
width = 100,
canSort = false,
autoResize = false,
Compare = null,
DrawCell = (cellRect, data, rowIndex, isSelected, isFocused) =>
{
data.headImage = (Texture)EditorGUI.ObjectField(cellRect, data.headImage, typeof(Texture), true);
},
});
表格视图
然后通过上面的表格行和表格列便可以生成一个表格视图：
TableView<Student> _tableView = new TableView<Student>(_students, _tableColumns);
此时，我们调用他的OnGUI方法便可以直接绘制出表格：
_tableView.OnGUI(new Rect(0, 0, width, height));
如下图，由于_students的默认数据长度为0，所以现在一条数据也没有：
我们点击右键，可以添加数据，或删除已选数据：
表格视图的基本使用就这么简单，如下是demo源码：
public class TestWindow : HTFEditorWindow
{
[MenuItem("Test/Table Window")]
private static void OpenWindow()
{
GetWindow<TestWindow>();
}
private List<Student> _students;
private List<TableColumn<Student>> _tableColumns;
private TableView<Student> _tableView;
protected override void OnEnable()
{
base.OnEnable();
_students = new List<Student>();
_tableColumns = new List<TableColumn<Student>>();
_tableColumns.Add(new TableColumn<Student>()
{
headerContent = new GUIContent("姓名"),
width = 100,
canSort = true,
autoResize = false,
Compare = (a, b) =>
{
return a.name.CompareTo(b.name);
},
DrawCell = (cellRect, data, rowIndex, isSelected, isFocused) =>
{
data.name = EditorGUI.TextField(cellRect, data.name);
},
});
_tableColumns.Add(new TableColumn<Student>()
{
headerContent = new GUIContent("性别"),
width = 100,
canSort = true,
autoResize = false,
Compare = (a, b) =>
{
return a.sex.CompareTo(b.sex);
},
DrawCell = (cellRect, data, rowIndex, isSelected, isFocused) =>
{
data.sex = (Sex)EditorGUI.EnumPopup(cellRect, data.sex);
},
});
_tableColumns.Add(new TableColumn<Student>()
{
headerContent = new GUIContent("年龄"),
width = 100,
canSort = true,
autoResize = false,
Compare = (a, b) =>
{
return a.age.CompareTo(b.age);
},
DrawCell = (cellRect, data, rowIndex, isSelected, isFocused) =>
{
data.age = EditorGUI.IntField(cellRect, data.age);
},
});
_tableColumns.Add(new TableColumn<Student>()
{
headerContent = new GUIContent("班级"),
width = 100,
canSort = true,
autoResize = false,
Compare = (a, b) =>
{
return a.grade.CompareTo(b.grade);
},
DrawCell = (cellRect, data, rowIndex, isSelected, isFocused) =>
{
data.grade = EditorGUI.TextField(cellRect, data.grade);
},
});
_tableColumns.Add(new TableColumn<Student>()
{
headerContent = new GUIContent("家庭住址"),
width = 100,
canSort = true,
autoResize = false,
Compare = (a, b) =>
{
return a.address.CompareTo(b.address);
},
DrawCell = (cellRect, data, rowIndex, isSelected, isFocused) =>
{
data.address = EditorGUI.TextField(cellRect, data.address);
},
});
_tableColumns.Add(new TableColumn<Student>()
{
headerContent = new GUIContent("实体"),
width = 100,
canSort = false,
autoResize = false,
Compare = null,
DrawCell = (cellRect, data, rowIndex, isSelected, isFocused) =>
{
data.entity = (GameObject)EditorGUI.ObjectField(cellRect, data.entity, typeof(GameObject), true);
},
});
_tableColumns.Add(new TableColumn<Student>()
{
headerContent = new GUIContent("颜色"),
width = 100,
canSort = false,
autoResize = false,
Compare = null,
DrawCell = (cellRect, data, rowIndex, isSelected, isFocused) =>
{
data.col = EditorGUI.ColorField(cellRect, data.col);
},
});
_tableColumns.Add(new TableColumn<Student>()
{
headerContent = new GUIContent("头像"),
width = 100,
canSort = false,
autoResize = false,
Compare = null,
DrawCell = (cellRect, data, rowIndex, isSelected, isFocused) =>
{
data.headImage = (Texture)EditorGUI.ObjectField(cellRect, data.headImage, typeof(Texture), true);
},
});
_tableView = new TableView<Student>(_students, _tableColumns);
}
protected override void OnBodyGUI()
{
base.OnBodyGUI();
_tableView.OnGUI(new Rect(0, 0, position.width, position.height));
}
public class Student
{
public string name;
public Sex sex;
public int age;
public string grade;
