write in data to html table

fender

good afternoon
There is an html table
I need to fill it with data
You should end up with a table with 5 columns and 5 rows
But in the end, everything is displayed in one column
Help find error
Thanks

void f(){
    QStringList massoil[size];

    _html += QString("<tr><td width=\"100%\" colspan=\"6\"><b><u>Result</u></b></td></tr>");
        _html += QString("<table border=\"1\" border-color=\"white\" width=\"100%\" cellspacing=\"0\" cellpadding=\"4\">");
          _html += QString("<tr></tr>");
            if ( cb_mass_oil->isChecked())
            {
                for (int col = 0; col < size; ++col)
                    for (int row = 0; row < 5; ++row)
                    {
                        if(row < massoil[col].size())
                            _html += QString("<tr><td width=\"40%\" align=\"center\" border=\"1\">%0</td></tr>")
                                    .arg(massoil[col][row]);
                        else
                            _html += QString("<tr><td width=\"40%\" align=\"center\" border=\"1\">%0</td></tr>")
                                    .arg("");
                    }
                   _html.replace(QRegularExpression("<tr(\\s[^>]*)?>(\\s*<td(\\s[^>]*)?>\\s*</td>\\s*)*</tr>", QRegularExpression::MultilineOption), "");
            }

move the row loop outside the column loop and don't close your <tr> tag at every column.
Well formatted html is a dialect of xml so it's usually cleaner to use QXmlStreamWriter to create html rather than manually piece together strings

Hi,

@fender said in write in data to html table:

QString("<tr><td width="40%" align="center" border="1">%0</td></tr>")

You are only adding rows with single cells in them.

The logic would be:

    for each row:
        add `<tr>` 
        for each column:
             add `<td>"whaterever"</td>`
        add`</tr>`
