Problema e MWE

Eu gostaria de aumentar a largura da longtblrtabela a seguir tanto quanto a largura máxima da página permitida, que deveria ser - eu acho - tão larga quanto o texto, ou seja, da margem esquerda até a margem direita da página. Em outras palavras, gostaria de deixar a tabela a seguir tão larga quanto o texto, da margem esquerda para a margem direita.

No entanto, eu teria uma restrição. Eu gostaria de manter as mesmas larguras das colunas seguintes

colspec={m{0.9cm} m{0.1cm} m{0.6cm} m{1cm} m{3cm} m{6cm} m{1.5cm}},

exceto a 6ª coluna (aquela chamada Feature 2), que agora é 6cmlarga. Portanto, a ideia é trabalhar apenas com a largura da 6ª coluna.

Basicamente, gostaria de estender/aumentar a largura da 6ª coluna de forma que toda a largura da tabela atinja a largura máxima de página permitida.

Existe alguma maneira automática de fazer isso ou devo aumentar a largura da 6ª coluna, desde que, a olho nu, veja que as bordas esquerda e direita da minha tabela estão alinhadas com todo o texto do documento?

Espero que isso esteja suficientemente claro! Aqui segue meu MWE e a figura correspondente:

Answer 1

• Você pode aumentar a largura da 6ª coluna apenas reduzindo a largura da outra coluna. No seu caso eu reduziria a largura da 5ª e última coluna, para a 6ª coluna eu usaria Xo tipo de coluna, cuja largura é \textwidth- soma das larguras das colunas restantes.
• Para largura maior da 6ª coluna, você pode reduzir colsep.
• Como você pode ver, na 6ª coluna centralizei tblra tabela inserida -
