Example 1:
Javascript
function setup() {   createCanvas(500, 300);   textSize(16);     text("Click on the button to get " +        "all the values of the table",        20, 20);     setBtn =     createButton("Get all table values");   setBtn.position(30, 40);   setBtn.mouseClicked(showTable);     // Create the table   table = new p5.Table();     // Add two columns   table.addColumn("name");   table.addColumn("id");     // Add some rows to the table   let newRow = table.addRow();   newRow.setString("name", "Suresh");   newRow.setString("id", 1);     newRow = table.addRow();   newRow.setString("name", "Ishaan");   newRow.setString("id", 22);     newRow = table.addRow();   newRow.setString("name", "Kumar");   newRow.setString("id", 32);     newRow = table.addRow();   newRow.setString("name", "Ram");   newRow.setString("id", 332);     newRow = table.addRow();   newRow.setString("name", "Shreya");   newRow.setString("id", 19); }   function showTable() {   clear();   text("The values of a tableRow " +        "are retrieved using the get() method",        20, 20);     // Show all the columns present   for (let c = 0; c < 2; c++) {     text(table.columns,          20 + 100 * c, 80);   }     // Show all the rows currently   // present in the table   for (let r = 0; r < 5; r++) {           // Using the name column     text(table.rows[r].get("name"),          20, 120 + 20 * r);       // Using the id column     text(table.rows[r].get("id"),          120, 120 + 20 * r);   } } |

Example 2:
Javascript
function setup() {   createCanvas(500, 300);   textSize(18);     text("Click on the button to get " +        "that value in the table",        20, 20);       text("Enter the row needed:", 20, 60);     rowInp = createInput();   rowInp.position(30, 80);   rowInp.size(30, 20);     text("Enter the column needed:", 20, 120);     colInp = createInput();   colInp.position(30, 140);   colInp.size(30, 20);     setBtn =     createButton("Get value at row and column");   setBtn.position(30, 180);   setBtn.mouseClicked(getValueAt);     // Create the table   table = new p5.Table();     setTableData(); }   function setTableData() {     // Add 5 columns and rows to the table   for (let i = 0; i < 5; i++) {     table.addColumn("Column " + i);     table.addRow();   }     for (let r = 0; r < 5; r++) {     for (let c = 0; c < 5; c++) {         // Set the value at the given       // column and row of the table       table.set(r, c, r + "::" + c);     }   } }   function getValueAt() {   clear();   let rowToGet = int(rowInp.value());   let colToGet = int(colInp.value());     if (rowToGet < table.getRowCount() &&       colToGet < table.getColumnCount()) {     text("The value at row " + rowToGet +          " and column " + colToGet +          " is:", 20, 240);       // Get the row of the table     let tableRow = table.rows[rowToGet];       // Get the value of the given column     // from the row using the get() method     text(tableRow.get(colToGet), 30, 260);   }   else    text("Please enter correct row " +          "and column values", 20, 240);     text("Click on the button to get " +        "that value in the table", 20, 20);   text("Enter the row needed:", 20, 60);   text("Enter the column needed:", 20, 120); } |
