There's no need to push table food. It was only during WWII that babies were started on table food as young as 6 months (and it was because mums couldn't bring their babies into the factories with them... and formulas were just that formulas/recipes printed in magazines and newspapers of oils and things to mix together for the older kids and grandparents to feed the babies while moms were working.) Prior to WWII most women nursed exclusively until over 1 year old (first birthday cake was often the first table food they had), and continued to nurse until age 2.
In our family, we follow the old model as far as no tablefood beyond "tasting" until a year. Kind of common sense... it avoids the whole digestive problems that plague modern parents at right around 6mo (when they start table food)... gas, colic, constipation, major changes (for the worse) in sleep schedules. Then we do the "explore the world through food" from 1-2ish, getting in as many flavors as possible, and bypassing bland/boring baby/toddler food entirely.
There are ALWAYS babies whose digestive systems are ready early (just like there are early walkers, talkers, etc)... but most aren't. LOL... I knew a 6month old who was walking. Most don't. So if he skips table food except for occasionally for the next few months... don't sweat it.
ALSO when babies are sick (actually when humans are sick) our digestive systems shut down (so our bodies can shunt the energy to our immune systems instead). For adults, we just don't eat. Babies are growing so much though, that they still need to. Hence why so many revert back to 100% milk or formula for a few weeks when they're ill. After those few weeks... Voila.
