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);
