end	object	yes
end.columnIndex	integer	yes
end.rowIndex	integer	yes
start	object	yes
start.columnIndex	integer	yes
start.rowIndex	integer	yes
target	TableAddress	yes	TableAddress
target.kind	"block"	yes	Constant: "block"
target.nodeId	string	yes
target.nodeType	"table"	yes	Constant: "table"

Variant 2 (required: nodeId)

Field	Type	Required	Description

Example request

{
  "end": {
    "columnIndex": 1,
    "rowIndex": 1
  },
  "start": {
    "columnIndex": 1,
    "rowIndex": 1
  },
  "target": {
    "kind": "block",
    "nodeId": "node-def456",
    "nodeType": "table"
  }
}

Output fields

Variant 1 (success=true)

Field	Type	Required	Description
success	true	yes	Constant: true
table	TableAddress	no	TableAddress
table.kind	"block"	no	Constant: "block"
table.nodeId	string	no
table.nodeType	"table"	no	Constant: "table"
trackedChangeRefs	EntityAddress[]	no

Variant 2 (success=false)

Field	Type	Required	Description
failure	object	yes
failure.code	enum	yes	"NO_OP", "INVALID_TARGET", "TARGET_NOT_FOUND", "CAPABILITY_UNAVAILABLE"
failure.details	any	no
failure.message	string	yes
success	false	yes	Constant: false

When present, result.table is the follow-up address to reuse after this call. For non-destructive table-targeted mutations, pass result.table.nodeId to the next table operation instead of re-running find(). Destructive operations may omit table.
