for example, there is no problem with using mock data, and an exception will occur if you replace it with an api address. 
 after testing, the following problems are found: 
 post the st component first: 
 < st-sharpst [data] = "queryData" [columns] = "columns" size="small" (checkboxChange) = "checkboxChange ($event)" > < / st > 
 ts file: 
 queryData = "api/xxxx". 
 api returns data: 
 {
"Total": 2021,
"List": [
    {
        "PlantCode": "F1331",
        "PlantName": "F1331",
        "UpdateDate": "2019/01/24",
        "UpdateUser": "Z12083050"
    }
]} / / so that the data list will not be displayed
 if queryData = List, the data list can be displayed normally, but there is no way to use server paging, or with st.reload, you can only override the search method. 
  @ cipchk  Please take a look at it for me ~ Thank you ~
