trim()

Removes whitespace characters from the beginning and end of a String. In addition to standard whitespace characters such as space, carriage return, and tab, this function also removes the Unicode "nbsp" (U+00A0) character and the zero width no-break space (U+FEFF) character.

• Table table;
  
  void setup() {
  
   table = new Table();
  
   table.addColumn("name");
   table.addColumn("type");
  
   TableRow newRow = table.addRow();
   newRow.setString("name", " Lion");
   newRow.setString("type", "Mammal");
  
   newRow = table.addRow();
   newRow.setString("name", "Snake ");
   newRow.setString("type", "Reptile");
  
   newRow = table.addRow();
   newRow.setString("name", " Mosquito ");
   newRow.setString("type", "Insect");
   
   println(table.getStringColumn("name"));
   
   table.trim();
   
   println(table.getStringColumn("name"));
  }
  
  // Sketch prints:
  // [0] " Lion"
  // [1] "Snake "
  // [2] " Mosquito "
  // [0] "Lion"
  // [1] "Snake"
  // [2] "Mosquito"
  

• String s1 = " Somerville MA ";
  println(s1); // Prints " Somerville MA "
  String s2 = trim(s1);
  println(s2); // Prints "Somerville MA"
  
  String[] a1 = { " inconsistent ", " spacing" }; // Note spaces
  String[] a2 = trim(a1);
  printArray(a2);
  // Prints the following array contents to the console:
  // [0] "inconsistent"
  // [1] "spacing"
