Example 1:
Javascript
function setup() {   createCanvas(600, 300);   textSize(18);     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", "Mary");   newRow.setString("id", "id-1");     newRow = table.addRow();   newRow.setString("name", "Nezuko");   newRow.setString("id", "id-12");     newRow = table.addRow();   newRow.setString("name", "Ishigaki");   newRow.setString("id", "id-121");     newRow = table.addRow();   newRow.setString("name", "Sam");   newRow.setString("id", "id-23");     newRow = table.addRow();   newRow.setString("name", "Max");   newRow.setString("id", "id-45");     newRow = table.addRow();   newRow.setString("name", "Mikasa");   newRow.setString("id", "id-132"); }   function showTable() {   clear();   text("The values each tableRow is " +        "retrieved using the getString() method",      20, 20);     // Show all the columns present   for (let c = 0; c < table.getColumnCount(); c++) {     text(table.columns, 20 + 160 * c, 80);   }     // Show all the rows currently   // present in the table   for (let r = 0; r < table.getRowCount(); r++) {           // Get the table row from the table     let table_row = table.rows[r];       // Getting the name column from     // the table row     text(table_row.getString("name"),       20, 120 + 20 * r);       // Getting the id column from     // the table row     text(table_row.getString("id"),       180, 120 + 20 * r);   } } |
Output:
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 row and column", 20, 60);     rowInp = createInput();   rowInp.position(30, 80);   rowInp.size(30, 20);     colInp = createInput();   colInp.position(70, 80);   colInp.size(30, 20);     setBtn =     createButton("Get value at row and column");   setBtn.position(30, 110);   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, 160);       // Get the table row from the table     let table_row = table.rows[rowToGet];           // Print the column from the table row     text(table_row.getString(colToGet),          20, 180);   }   else    text("Please enter correct row " +          "and column values", 20, 160);     text("Click on the button to get " +        "that value in the table", 20, 20);   text("Enter row and column", 20, 60); } |
