[jira] [Updated] (ARROW-18014) Add copy functions to Table

     [ https://issues.apache.org/jira/browse/ARROW-18014?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Larry White updated ARROW-18014:
--------------------------------
    Description: 
Add copyVector() and copy() (to copy the whole Table) to the Table interface.

 

The copy vector methods support the use-case where someone really needs a vector (rather than, say, a FieldReader), but we don't want to break immutability. 

 

The copy table method supports the use-case of wanted to make a working copy of a table before converting the original to a VectorSchemaRoot
