MySQL-如何在多列html表中显示，MySQL表的单列

我想知道如何在我的php文件中用html显示一个有多列的表，但在该表中，列只显示来自mysqli 的单列结果

我现在拥有的是：

<?php
include "dbinc.php";
$con=mysqli_connect($servername,$username,$password,$database);
$letramasculinos = mysqli_query($con,"SELECT nome FROM nomes WHERE nome LIKE '$_POST[letra]%' AND sexo = 'm';");
$letrafemininos = mysqli_query($con,"SELECT nome FROM nomes WHERE nome LIKE '$_POST[letra]%' AND sexo = 'f';");
     (more code...)
echo "<table style='display: inline-block;' width='150px' border='1' bgcolor='#6699FF'>";
while($row = mysqli_fetch_array($letramasculinos))
{
echo "<tr>";
echo "<td><center>" . $row['nome'] . "</center></td>";
echo "</tr>";
echo "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;";
echo "<table style='display: inline-block;' width='150px' border='1' bgcolor='#FF99FF'>";
while($row = mysqli_fetch_array($letrafemininos))
{
echo "<tr>";
echo "<td><center>" . $row['nome'] . "</center></td>";
echo "</tr>";
}
echo "</table>";
}
     (more code...)
?>

在这个示例代码中，它显示了2个有1列的HTML表，但由于条目太多，我希望在每个表中将该列除以3列（或除以4或5，等等）。

我该怎么做？

示例：

我有什么和我想要什么
