default AsyncTable<AdvancedScanResultConsumer> getTable(TableName tableName) {
    return getTableBuilder(tableName).build();
  }
Retrieve an {@link AsyncTable} implementation for accessing a table.
<p>
The returned instance will use default configs. Use {@link #getTableBuilder(TableName)} if you
want to customize some configs.
<p>
This method no longer checks table existence. An exception will be thrown if the table does not
exist only when the first operation is attempted.
<p>
The returned {@code CompletableFuture} will be finished directly in the rpc framework's
callback thread, so typically you should not do any time consuming work inside these methods.
And also the observer style scan API will use {@link AdvancedScanResultConsumer} which is
designed for experts only. Only use it when you know what you are doing.
@param tableName the name of the table
@return an AsyncTable to use for interactions with this table
