I have a table and am trying to find a specific string within it, once found I’m trying to get a string from next to it. How would I go about doing that?

int findRowIndex(java.lang.String value,
int column)

See Table

Example



// Sketch saves the following to a file called "new.csv":
// id,species,name
// 0,Panthera leo,Lion etc. 

void setup() {

  size(200, 60);

  // make table 
  Table table = makeTable();
  // show table 
  showTable(table); 
  // save table 
  saveTable(table, "data/new.csv");

  // search table
  println("-----------");
  for (int i_Column=0; i_Column<table.getColumnCount(); i_Column++) {
    int resultRowIndex = table.findRowIndex("Tiger2", i_Column);
    if (resultRowIndex>-1) {
      println(resultRowIndex);
      String result1=table.getString( resultRowIndex, i_Column );
      println(result1);
      String resultNext=table.getString( resultRowIndex, i_Column+1 );
      println(resultNext);
    }//if
  }//for

  // test search  
  println("--------");
  int result =  table.findRowIndex("Panthera leo", "species");
  println(result);
}//func 

//--------------------------------------------------------------------------------------

  // Prints a String of Spaces to be inserted after "prev" to fill the space up to a position 17 which is the end of the column ("|")
