The lazy way is to do
tst_tab = tst_tab[c(2,1), c(2,1)]
The less lazy way is something like
tst_tab <- table(predicted = factor(tst_pred, levels = c("Yes", "No")), actual = factor(default_tst$default, levels = c("Yes",
"No")))

R-Help community is there an simple straight forward way of changing
my confusion table output to list "Yes" before "No" rather than "No"
before "Yes" - R default.
# Making predictions on the test set.
tst_pred <- ifelse(predict(model_glm, newdata = default_tst, type =
"response") > 0.5, "Yes", "No")
tst_tab <- table(predicted = tst_pred, actual = default_tst$default)
tst_tab
## actual
## predicted No Yes
## No 4817 113
## Yes 18 52
