By default, the TableSheet will just interact with the local data manager. If you want to sync the changed data with your remote database, just enable the AutoSync or Batch mode first.
This demo uses Batch mode.
AutoSync Mode
This mode is mainly suitable for low frequency data operation scenarios. Once you use buttons in the row action or APIs to interact with the rows, the request with corresponding changes will be initiated and sent to the server immediately.
To enable the AutoSync mode in table initialization:
Batch Mode
This mode is mainly suitable for scenarios where data is frequently manipulated. It will store each row operation in the order, and then package all the changes into a collection and send it to the server at one time in order to save network resources.
To enable the Batch mode and specify a BatchApiUrl in table initialization:
Then you can submit or discard all the changes:
Get Changes
You can also get the changes before save them to server.

An object array, where each object contains a 'type' property.
This operation type could be 'update', 'insert', or 'delete'.
The 'dataItem' property is the current record.
The 'sourceIndex' property is the record index.
The optional 'oldDataItem' property is the original record.
For example:
[ {"type":"delete","dataItem":{...}, "sourceIndex":5},
{"type":"insert","dataItem":{...}, "sourceIndex":3},
{"type":"update","dataItem":{...}, "oldDataItem":{...}, "oldDataItem":{...}, "sourceIndex":1}]
An object array, where each object contains a 'succeed' property which indicates an operation's success or failure, and an optional 'data' property, which is the current record and only for the 'insert' operation.
For example:
[{"succeed":true}, {"succeed":false}, {"succeed": true}]
