下面是代码实现：

MainTaskRowComData

using Unity.Entities;
using System;
using TMPro;
using UnityEngine.UI;

[Serializable]
public struct MainTaskRowComData : ISharedComponentData
{ 
    //ComData
    public TextMeshProUGUI txt_IndexID;
    public TextMeshProUGUI txt_TaskName;
    public Button btn_Edit;
    public Button btn_Delete;

}


public class MainTaskRowComDataProxy : SharedComponentDataProxy<MainTaskRowComData>
{
    public void On_EditClick(TextMeshProUGUI txtid)
    {
        UnityEngine.Debug.Log("on click:" + txtid.text);
    }
}

MainTaskRow_System

    ComponentGroup m_MainGroup;

        //base.OnCreateManager();
        //根据类型找 MainTaskRowComData
        m_MainGroup = GetComponentGroup(typeof(MainTaskRowComData));
        //m_MainGroup.CalculateLength() is 0

    }
    protected override void OnStartRunning()
    {

        //base.OnStartRunning();
        int count = m_MainGroup.CalculateLength();
        Debug.Log("row:" + count);// output count:3

        var lst = m_MainGroup.GetSharedComponentDataArray<MainTaskRowComData>();
