- value: It is a String or Number that specifies the value that has to be stored.
Below example illustrates the set() method in p5.js:
Example 1:
function setup() {   createCanvas(500, 300);   textSize(18);     text("Click on the button to set the" +        " values of the table", 20, 20);     setBtn = createButton("Add Table Values");   setBtn.position(30, 40);   setBtn.mouseClicked(setTableData);     // Create the table   table = new p5.Table();     // Add 5 columns and rows to the table   for (let i = 0; i < 5; i++) {     table.addColumn("Column " + i);     table.addRow();   } }   function setTableData() {   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);     }   }     showTable(); }   function showTable() {   clear();     text("Click on the button to set the" +        " values of the table", 20, 20);     // Show all the columns present   for (let c = 0; c < 5; c++) {     text(table.columns, 20 + 80 * c, 80);   }     // Show all the rows currently   // present in the table   for (let r = 0; r < 5; r++) {     for (let c = 0; c < 5; c++) {       text(table.getString(r, c),            20 + 80 * c,            100 + 20 * r);     }   } } |
Output:
Example 2:
function setup() {   createCanvas(500, 300);   textSize(18);     changeBtn =     createButton("Modify Table");   changeBtn.position(30, 40);   changeBtn.mouseClicked(modifyTable);     // Create the table   table = new p5.Table();     // Add 5 columns and rows to the table   for (let i = 0; i < 5; i++) {     table.addColumn("Column " + i);     table.addRow();   }     setTableData();     // Display the table   showTable(); }   function setTableData() {   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);     }   }     showTable(); }   function modifyTable() {   for (let r = 0; r < 5; r++) {     for (let c = 0; c < 5; c++) {         // If the index of the table is       // a diagonal, set it to "XX"       if (r == c) table.set(r, c, "XX");     }   }     showTable(); }   function showTable() {   clear();    text("Click on the button to set the" +        " values of the table", 20, 20);     // Show all the rows currently   // present in the table   for (let r = 0; r < 5; r++) {     for (let c = 0; c < 5; c++) {       text(table.getString(r, c),            20 + 80 * c,            80 + 20 * r);     }   } } |
