p5.js | saveTable() Function

  • Last Updated : 16 Mar, 2020

The saveTable() function is used to save a p5.Table object to a file. The format of the file saved can be defined as a parameter to the function. By default, it saves a text file with comma-separated-values, however, it can be used to save it using-tab separated-values or generate an HTML table from it.

Syntax:

saveTable( Table, filename, options )

Parameters: This function accept three parameters as mentioned above and described below:

  • Table: This is a p5.Table object that would be saved to the file.
  • filename: It specifies the string that is used as the filename of the saved file.
  • options: It is a string which denotes the format of the table to be saved. It can be either “csv” which saves the table using comma-separated-values, “tsv” which saves the table using tab-separated-values, or “html” which generates an HTML table. It is an optional parameter.

Below example illustrates the saveTable() function in p5.js:

Example:






function setup() {
  createCanvas(600, 300);
  textSize(20);
   
  text("Click on the button below to "
        + "save the Table Object", 20, 20);
    
  text("Select the output format:", 20, 60);
   
  // Create radio button for choosing
  // file format to save the table
  radio = createRadio();
  radio.position(30, 80);
  radio.option('csv');
  radio.option('tsv');
  radio.option('html');
   
  // Create a button for saving the Table object
  saveBtn = createButton("Save Table to file");
  saveBtn.position(30, 120);
  saveBtn.mousePressed(saveFile);
   
  // Create the table for saving to file
  table = new p5.Table();
   
  table.addColumn('Invention');
  table.addColumn('Inventors');
   
  let tableRow = table.addRow();
  tableRow.setString('Invention', 'Telescope');
  tableRow.setString('Inventors', 'Galileo');
   
  tableRow = table.addRow();
  tableRow.setString('Invention', 'Steam Engine');
  tableRow.setString('Inventors', 'James Watt');
   
  tableRow = table.addRow();
  tableRow.setString('Invention', 'Radio');
  tableRow.setString('Inventors', 'Guglielmo Marconi');
}
   
function saveFile() {
   
  // Get the output format selected
  // from the radio buttons
  outputFormat = radio.value();
   
  // Save the table to file with the given format
  saveTable(table, 'tableOutput', outputFormat);
}
