‘table.select’ method return new Table with specific columns.
Example
Table resultedTable = table.select("FirstName", "LastName");
package com.sample.app;
import tech.tablesaw.api.IntColumn;
import tech.tablesaw.api.StringColumn;
import tech.tablesaw.api.Table;
public class App {
public static void main(String args[]) {
int[] empIds = { 1, 2, 3, 4, 5, 6 };
String[] firstNames = { "Hari", "Ram", "Sowmya", "Chamu", "Swethank", "Chamu" };
String[] lastNames = { "Krishna", "Gurram", "Maj", "Maj", "Baji", "Gurram" };
Table table = Table.create().addColumns(IntColumn.create("Employee Id", empIds))
.addColumns(StringColumn.create("FirstName", firstNames))
.addColumns(StringColumn.create("LastName", lastNames));
Table resultedTable = table.select("FirstName", "LastName");
System.out.println(table.print());
System.out.println("\n" + resultedTable.print());
}
}
Output
