I'm trying to create a table in javascript and put a header on it. I tried to incorporate the answer from this SO question but perhaps I didn't include it in the right place. The body of the table works perfectly, but the header appends as a bunch of text to the top instead of a nicely formatted header. Here is the code:
function generate_table() {
// get the reference for the body
var body = document.getElementsByTagName("body")[0];
// creates a <table> element and a <tbody> element
var tbl = document.createElement("table");
//var header = document.createElement("header");
var header = '<tr><th>Country</th><th>City</th></tr>';
//var header = "<th>Header</th>";
var tblBody = document.createElement("tbody");
// creating all cells
for (var i = 0; i < results.weak_sent.length; i++) {
// creates a table row
var row = document.createElement("tr");
for (var j = 0; j < 2; j++) {
// Create a <td> element and a text node, make the text
// node the contents of the <td>, and put the <td> at
// the end of the table row
var cell = document.createElement("td");
if (j == 0) {
var cellText = document.createTextNode(results.weak_sent_num[i]);
} else {
var cellText = document.createTextNode(results.weak_sent[i]);
}
cell.appendChild(cellText);
row.appendChild(cell);
}
// add the row to the end of the table body
tblBody.appendChild(row);
}
tbl.append(header)
// put the <tbody> in the <table>
tbl.appendChild(tblBody);
// appends <table> into <body>
body.appendChild(tbl);
// sets the border attribute of tbl to 2;
tbl.setAttribute("border", "2");
}
It prints the rows and the columns correctly, but instead of interpreting the <tr><th> as HTML tags it just prints them out as text. I've also noticed that if the table text contains any HTML tags, like <strong> or <b>, they are returned as plain text as well. How can I make them be read as HTML. I have a CSS page as well but there's no reset or anything (intentionally) affecting the use of bold or tables. Here's my result
<tr><th>Country</th><th>City</th></tr>
1 Row 1 text
2 Row <b>2</b> text

Reset to default 2Solution1
The way you are appending tbody rows, you can insert the heading as well. So instead of tbl.append(header) and defining the header string, you can use something like below:
results = {
weak_sent: [
"row 1 data",
"row 2 data"
],
weak_sent_num: [1,2]
}
function generate_table() {
// get the reference for the body
var body = document.getElementsByTagName("body")[0];
// creates a <table> element and a <tbody> element
var tbl = document.createElement("table");
//var header = document.createElement("header");
// var header = '<tr><th>Country</th><th>City</th></tr>';
var header= document.createElement('thead')
var headingRow = document.createElement('tr')
var headingCell1 = document.createElement('td')
var headingText1 = document.createTextNode('country')
headingCell1.appendChild(headingText1)
headingRow.appendChild(headingCell1)
var headingCell2 = document.createElement('td')
var headingText2 = document.createTextNode('City')
headingCell2.appendChild(headingText2)
headingRow.appendChild(headingCell2)
header.appendChild(headingRow)
tbl.appendChild(header)
//var header = "<th>Header</th>";
var tblBody = document.createElement("tbody");
// creating all cells
for (var i = 0; i < results.weak_sent.length; i++) {
// creates a table row
var row = document.createElement("tr");
for (var j = 0; j < 2; j++) {
// Create a <td> element and a text node, make the text
// node the contents of the <td>, and put the <td> at
// the end of the table row
var cell = document.createElement("td");
if (j == 0) {
var cellText = document.createTextNode(results.weak_sent_num[i]);
} else {
var cellText = document.createTextNode(results.weak_sent[i]);
}
cell.appendChild(cellText);
row.appendChild(cell);
}
// add the row to the end of the table body
tblBody.appendChild(row);
}
// This is for the quick solution
// tbl.innerHTML = header
// put the <tbody> in the <table>
tbl.appendChild(tblBody);
// appends <table> into <body>
body.appendChild(tbl);
// sets the border attribute of tbl to 2;
tbl.setAttribute("border", "2");
}
generate_table()Solution2 As a quick solution you can use innerHTML property, as shown below.
results = {
weak_sent: [
"row 1 data",
"row 2 data"
],
weak_sent_num: [1,2]
}
function generate_table() {
// get the reference for the body
var body = document.getElementsByTagName("body")[0];
// creates a <table> element and a <tbody> element
var tbl = document.createElement("table");
//var header = document.createElement("header");
var header = '<tr><th>Country</th><th>City</th></tr>';
//var header = "<th>Header</th>";
var tblBody = document.createElement("tbody");
// creating all cells
for (var i = 0; i < results.weak_sent.length; i++) {
// creates a table row
var row = document.createElement("tr");
for (var j = 0; j < 2; j++) {
// Create a <td> element and a text node, make the text
// node the contents of the <td>, and put the <td> at
// the end of the table row
var cell = document.createElement("td");
if (j == 0) {
var cellText = document.createTextNode(results.weak_sent_num[i]);
} else {
var cellText = document.createTextNode(results.weak_sent[i]);
}
cell.appendChild(cellText);
row.appendChild(cell);
}
// add the row to the end of the table body
tblBody.appendChild(row);
}
// This is for the quick solution
tbl.innerHTML = header
// put the <tbody> in the <table>
tbl.appendChild(tblBody);
// appends <table> into <body>
body.appendChild(tbl);
// sets the border attribute of tbl to 2;
tbl.setAttribute("border", "2");
}
