The set() method of p5.Table in p5.js is used to store the given value to the given row and column of the table. The row can be specified by the row ID and the column can be specified by its column ID or name.
Syntax:
set( row, column, value )
Parameters: This function accepts three parameters as mentioned above and described below:
- row: It is a Number that denotes the row ID of the row.
- column: It is a String or Number that denotes the column name or ID of the column.
- 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); } } } |
